Porażenie mózgowe
Patofizjologia i mechanizm

Porażenie mózgowe (CP) to grupa trwałych zaburzeń rozwoju ruchu i postawy, wynikających z niepostępujących uszkodzeń mózgu powstałych w okresie prenatalnym, okołoporodowym lub wczesnym postnatalnym. Dotyka około 1 na 500 noworodków, a etiologia jest wieloczynnikowa, z dominującym udziałem czynników przedporodowych (około 80%). Kluczowe patologie to krwotok dokomorowy (IVH) i leukomalacja okołokomorowa (PVL), szczególnie u wcześniaków, które uszkadzają drogi korowo-rdzeniowe i prowadzą do spastycznego porażenia mózgowego – najczęstszego typu CP. Patogeneza obejmuje niedokrwienie/hipoksję oraz stan zapalny z udziałem cytokin prozapalnych (IL-6, TNF-α), stres oksydacyjny i ekscytotoksyczność glutaminianową. Genetyczne uwarunkowania odgrywają rolę w około 25% przypadków, co podkreśla złożoność mechanizmów etiologicznych. Obrazowanie MRI i DTI pozwala na identyfikację uszkodzeń istoty białej i korelację z ciężkością deficytów motorycznych.

Patogeneza porażenia mózgowego

Porażenie mózgowe (CP, cerebral palsy) definiuje się jako grupę trwałych zaburzeń rozwoju ruchu i postawy, powodujących ograniczenie aktywności, które przypisuje się niepostępującym zaburzeniom powstałym w rozwijającym się mózgu płodu lub niemowlęcia12. Jest to najczęstsza przyczyna ciężkiej niepełnosprawności neurologicznej u dzieci, dotykająca około 1 na 500 noworodków, z szacowaną światową częstością występowania wynoszącą 17 milionów osób3. Zrozumienie fizjopatologii porażenia mózgowego ma kluczowe znaczenie dla opracowania strategii ochronnych i terapeutycznych4.

Wieloczynnikowa etiologia

Porażenie mózgowe nie jest pojedynczym zaburzeniem czy chorobą w tradycyjnym znaczeniu, ale klinicznym opisem dzieci, które mają wspólne cechy niepostępującego uszkodzenia lub uszkodzenia mózgu nabytego w okresie prenatalnym, okołoporodowym lub wczesnym postnatalnym56. Etiologia porażenia mózgowego jest wieloczynnikowa, z różnorodnymi i złożonymi mechanizmami przyczynowymi7.

Klasycznie uważano, że przerwanie dopływu tlenu do płodu lub asfiksja mózgu jest głównym czynnikiem przyczynowym wyjaśniającym późniejsze wystąpienie porażenia mózgowego8. Jednakże badania wykazały, że około 80% przypadków porażenia mózgowego jest spowodowanych przez czynniki przedporodowe, a tylko około 10% przez zdarzenia poporodowe910. Większość przypadków jest wynikiem problemów występujących podczas ciąży, ale mogą również wystąpić podczas porodu lub krótko po nim11.

Okres prenatalny i czynniki ryzyka

Czynniki ryzyka związane z porażeniem mózgowym obejmują1213:

  • Poród przedwczesny (znaczący czynnik ryzyka)
  • Bycie bliźniakiem
  • Określone infekcje lub narażenie na metylortęć w czasie ciąży
  • Trudny poród
  • Urazy głowy w pierwszych latach życia
  • Ograniczenie wzrostu wewnątrzmacicznego
  • Nadużywanie substancji przez matkę
  • Stan przedrzucawkowy
  • Zapalenie błon płodowych
  • Nieprawidłowa patologia łożyska
  • Aspiracja smółki
  • Hipoglikemia okołoporodowa
  • Predyspozycje genetyczne

14

Nowsze badania sugerują, że dziedziczne przyczyny genetyczne odgrywają rolę w 25% przypadków, podczas gdy wcześniej uważano, że tylko 2% przypadków jest uwarunkowanych genetycznie15. Badania ujawniły, że nieprawidłowe wyniki całkowitego sekwencjonowania eksomu lub genomu można zaobserwować u ponad 30% pacjentów z porażeniem mózgowym16.

Patofizjologia uszkodzenia mózgu

Porażenie mózgowe jest spowodowane nieprawidłowym rozwojem lub uszkodzeniem części mózgu, które kontrolują ruch, równowagę i postawę17. Uszkodzenie to może wystąpić przed urodzeniem, w trakcie porodu lub krótko po nim18. Problemy strukturalne w mózgu obserwuje się u 80% przypadków, najczęściej w obrębie istoty białej19.

Dwie główne patologie, które odgrywają kluczową rolę w rozwoju porażenia mózgowego to20:

  • Krwotok dokomorowy (IVH) – zwiększa ryzyko porażenia mózgowego wraz ze wzrostem jego ciężkości
  • Leukomalacja okołokomorowa (PVL) – jest to stan niedorozwiniętej istoty białej w mózgu otaczającej komory, będący główną przyczyną porażenia mózgowego u wcześniaków

2122

Drogi korowo-rdzeniowe składające się z zstępujących aksonów ruchowych przechodzą przez region okołokomorowy, który jest powszechnie uszkadzany w PVL i IVH, prowadząc do porażenia mózgowego23. Chociaż obie patologie zwiększają ryzyko porażenia mózgowego, leukomalacja okołokomorowa jest ściślej związana z porażeniem mózgowym i jest główną przyczyną u wcześniaków24.

Mechanizmy uszkodzenia mózgu

Patogeneza leukomalacji okołokomorowej wynika z dwóch ważnych czynników25:

  1. Niedokrwienie/hipoksja: Istota biała okołokomorowa noworodkowego mózgu jest zaopatrywana przez dystalne segmenty sąsiednich tętnic mózgowych, co czyni ją podatną na uszkodzenia związane z niedotlenieniem
  2. Infekcja/stan zapalny: Podwyższone poziomy cytokin prozapalnych, takich jak interleukina-6 (IL-6) i czynnik martwicy nowotworów alfa (TNF-α), zostały znalezione w mięśniach osób z porażeniem mózgowym i są powiązane z redukcją syntezy białek, zahamowaniem wzrostu i atrofią mięśni

2627

Biochemiczne kluczowe czynniki prowadzące do śmierci komórek lub utraty procesów komórkowych, obserwowane zarówno w warunkach niedotlenienia, jak i zapalnych, obejmują28:

  • Nadmierna produkcja cytokin prozapalnych
  • Stres oksydacyjny
  • Pozbawienie matczynych czynników wzrostu
  • Modyfikacje macierzy zewnątrzkomórkowej
  • Nadmierne uwalnianie glutaminianu, uruchamiające kaskadę ekscytotoksyczną

29

Ekscytotoksyczność to proces, w którym zwiększone poziomy zewnątrzkomórkowego glutaminianu stymulują oligodendrocyty do zwiększonego napływu wapnia, co stymuluje uwalnianie reaktywnych form tlenu, przyczyniając się do uszkodzeń oksydacyjnych30.

Typy porażenia mózgowego a uszkodzenie mózgu

Typ porażenia mózgowego odpowiada lokalizacji uszkodzenia mózgu31:

Typ porażenia mózgowego Obszar uszkodzenia mózgu Charakterystyczne objawy
Spastyczne porażenie mózgowe Kora ruchowa i drogi piramidowe Zwiększone napięcie mięśniowe, sztywność mięśni
Porażenie mózgowe atetoidowe Jądra podstawy i/lub móżdżek Kombinacja hipotonii i hipertonii, wahające się napięcie mięśniowe
Porażenie mózgowe ataktyczne Móżdżek Problemy z koordynacją ruchową
Porażenie mózgowe hipotoniczne Różne obszary Niskie napięcie mięśniowe, utrata siły i jędrności
Porażenie mózgowe mieszane Wiele obszarów mózgu Objawy dwóch lub więcej typów porażenia mózgowego

3233

Spastyczne porażenie mózgowe, najczęstszy typ, występuje, gdy uszkodzenie mózgu lub nieprawidłowy rozwój wpływa na obszary mózgu odpowiedzialne za kontrolę ruchu mięśni34. Uszkodzenie kory ruchowej zakłóca zdolność do kontrolowania ruchów, powodując, że stają się sztywne, szarpane lub „spastyczne”35.

Jeśli drogi piramidowe są uszkodzone, mózg nie może prawidłowo komunikować się z rdzeniem kręgowym, co upośledza kontrolę motoryczną36. Uszkodzenie to może nastąpić przed urodzeniem, podczas porodu lub krótko po porodzie37.

Wtórne zmiany w układzie mięśniowo-szkieletowym

Porażenie mózgowe charakteryzuje się hipertonią, czyli zwiększonym napięciem mięśniowym, prowadzącym do sztywnych i czasami bolesnych kończyn38. Patologiczne zmiany w mięśniach u osób z porażeniem mózgowym obejmują3940:

  • Upośledzony wzrost mięśni związany z dysfunkcją na poziomie komórkowym
  • Zaburzenia regeneracji mięśni połączone z ekspansją macierzy zewnątrzkomórkowej
  • Zwiększona ekspresja genów prozapalnych
  • Zmniejszony potencjał regeneracyjny z powodu zmniejszonej koncentracji i skuteczności komórek satelitarnych
  • Zmiany w biopsji mięśni charakteryzujące się zwiększoną zmiennością w rozmiarze włókien mięśniowych, dużą liczbą struktur „okrągłych” i „pogryzionych” zamiast wielokątnych oraz zwiększoną objętością przestrzeni zewnątrzkomórkowej

414243

Wczesne uszkodzenie centralnego neuronu ruchowego w porażeniu mózgowym prowadzi do zaburzenia różnicowania włókien mięśniowych i transmisji nerwowo-mięśniowej44. Zmiany w poziomie aktywności ruchowej w przypadkach uszkodzenia OUN i braku obciążenia wagowego zakłócają dojrzewanie „dorosłych” form miozyny45.

Rola czynników immunologicznych

Badania wykazały udział komórek immunokompetentnych w patogenezie porażenia mózgowego4647. Dostępne dane eksperymentalne i kliniczne wskazują na zaangażowanie komórek regulatorowych układu odpornościowego w tworzenie zaburzeń równowagi tkanki nerwowej i przewlekłości wrodzonego uszkodzenia mózgu48.

Rodzina interleukin, kluczowych mediatorów w odpowiedziach zapalnych, wykazuje zwiększoną ekspresję w różnych chorobach neurozapalnych, znacząco wpływając na ich początek i postęp49. Podwyższone poziomy IL w mózgach dzieci z porażeniem mózgowym, w przeciwieństwie do zdrowych rówieśników, odzwierciedlają podobne wzrosty w schorzeniach neurologicznych powiązanych z porażeniem mózgowym, wskazując na silny związek między porażeniem mózgowym a rodziną IL50.

Nowe podejścia terapeutyczne

Obecnie nie ma lekarstwa na porażenie mózgowe, ale postępy są czynione zarówno w zapobieganiu, jak i łagodzeniu uszkodzeń mózgu51. Tylko dwie strategie odniosły sukces w zmniejszaniu występowania porażenia mózgowego u dwuletnich dzieci52:

  1. Hipotermia u noworodków urodzonych w terminie z umiarkowaną encefalopatią noworodkową
  2. Podawanie siarczanu magnezu matkom w porodzie przedwczesnym

5354

Badane są potencjalne nowe metody leczenia, w tym terapia komórkami macierzystymi55. Terapie przeciwzapalne, zwłaszcza te ukierunkowane na interleukiny, wykazały skuteczność w modelach zwierzęcych, różniąc się od tradycyjnych metod postępowania w porażeniu mózgowym56. Ta zmiana sugeruje modulację IL jako obiecującą strategię terapeutyczną w dziecięcym porażeniu mózgowym57.

Wieloczynnikowe ścieżki przyczynowe w porażeniu mózgowym

Koncepcja ścieżek lub mechanizmów przyczynowych w powstawaniu porażenia mózgowego narodziła się z obserwacji, że pewne czynniki ryzyka są ze sobą powiązane58. Ścieżka przyczynowa odnosi się do sekwencji współzależnych zdarzeń, które kulminują w chorobie59.

Modele wieloczynnikowe

Modele dwuczynnikowe i wieloczynnikowe, które uwzględniają akumulację czynników ryzyka, mogą zidentyfikować synergistyczny wzrost ryzyka porażenia mózgowego, ale należy ustalić kolejność czasową i znaczenie kliniczne składników modelu60. Czynniki przedkoncepcyjne, w tym otyłość i wiek matki, należy wziąć pod uwagę, ponieważ mogą one modyfikować związki między porażeniem mózgowym a innymi czynnikami, które występują później w ciąży61.

Z powyższego wynika, że czynniki ryzyka w ścieżce są ze sobą powiązane i w większości przypadków addytywnie zwiększają ryzyko porażenia mózgowego62. Znaczenie identyfikacji i zrozumienia wszystkich tych złożonych ścieżek przyczynowych polega na formułowaniu strategii zapobiegawczych63.

Czynniki ryzyka okresu przedporodowego

Następujące matczyne i przedporodowe czynniki ryzyka statystycznie korelują z porażeniem mózgowym64:

  • Długi cykl miesiączkowy
  • Wcześniejsza utrata ciąży
  • Wcześniejsza utrata noworodka
  • Niepełnosprawność intelektualna matki
  • Zaburzenia tarczycy u matki, zwłaszcza niedobór jodu
  • Zaburzenia drgawkowe u matki
  • Historia porodu dziecka o wadze mniejszej niż 2000 g
  • Historia porodu dziecka z deficytem motorycznym, niepełnosprawnością intelektualną lub deficytem sensorycznym

65

Czynniki ryzyka okresu okołoporodowego

Następujące czynniki okołoporodowe są związane ze zwiększonym ryzykiem porażenia mózgowego66:

  • Wcześniactwo
  • Zapalenie błon płodowych
  • Nieprawidłowe ułożenie płodu
  • Asfiksja porodowa

67

Czynniki ryzyka okresu poporodowego

Następujące czynniki poporodowe mogą przyczynić się do porażenia mózgowego68:

  • Infekcje (np. zapalenie opon mózgowych, zapalenie mózgu)
  • Krwotok śródczaszkowy (np. z powodu wcześniactwa, malformacji naczyniowych lub urazu)
  • Leukomalacja okołokomorowa (u wcześniaków)
  • Hipoksja-niedokrwienie (np. z powodu aspiracji smółki)
  • Przetrwałe krążenie płodowe lub przetrwałe nadciśnienie płucne noworodka
  • Kernicterus

69

Zmiany strukturalne w mózgu

Badania obrazowe przy użyciu metody MRI wykazują nieprawidłowości u ponad 80% pacjentów z porażeniem mózgowym70. Badanie MRI ujawnia anomalie anatomiczne charakterystyczne dla poszczególnych typów porażenia mózgowego; umożliwia również lepsze zrozumienie patogenezy, etiologii uszkodzenia mózgu oraz zależności strukturalno-funkcjonalnych w porażeniu mózgowym71.

Obrazowanie tensora dyfuzji

Obrazowanie tensora dyfuzji (DTI) wykorzystuje ograniczenia w losowym ruchu protonów wody przez makrocząsteczki i mielinę, aby wizualizować szlaki istoty białej mózgu72. Może być używane do tworzenia dwu- i trójwymiarowych kolorowych map normalnej architektury istoty białej oraz do zapewnienia bardziej precyzyjnej identyfikacji dysgenezji i uszkodzenia istoty białej niż konwencjonalne obrazowanie73.

Metryki DTI (niższa anizotropia frakcyjna i wyższa dyfuzyjność poprzeczna) w zstępujących drogach piramidowych korelują z bardziej znacznym upośledzeniem motorycznym74.

Specyficzne typy uszkodzeń mózgu

Następujące typy uszkodzeń mózgu mogą prowadzić do spastycznego porażenia mózgowego75:

  • Dysgenezja mózgowa – nieprawidłowy rozwój mózgu
  • Leukomalacja okołokomorowa – uszkodzenie istoty białej otaczającej komory mózgowe
  • Krwotoki mózgowe – krwawienie w mózgu
  • Encefalopatia niedotlenieniowo-niedokrwienna – uszkodzenie mózgu spowodowane brakiem tlenu lub przepływu krwi

76

W spastycznej diplegii zarówno ruchowe drogi korowo-rdzeniowe, jak i drogi wzgórzowo-korowe są dotknięte77. Spastyczna diplegia jest spowodowana uszkodzeniem niedojrzałych oligodendrogli między 20 a 34 tygodniem ciąży78.

Spastyczna tetraplegia stanowi 20% dzieci z porażeniem mózgowym, a ten fenotyp kliniczny jest związany z porodem przedwczesnym, a obrazowanie neurologiczne pokazuje ciężką leukomalację okołokomorową i wielotorbielowatą encefalomalację korową79.

Pozapiramidowe porażenie mózgowe obejmuje fenotypy kliniczne choreoatetozy, dystonii lub dyskinezji i stanowi 15% przypadków porażenia mózgowego80. Większość przypadków jest obserwowana u niemowląt urodzonych w terminie i związana z encefalopatią niedotlenieniowo-niedokrwienną, kernicterusem, zaburzeniami neurometabolicznymi lub neurogenetycznymi81.

Mechanizmy towarzyszące

Zaburzenia przetwarzania sensorycznego

Porażenie mózgowe jest tradycyjnie postrzegane głównie jako zaburzenie ruchu, jednak coraz więcej dowodów wskazuje na współistniejące deficyty w przetwarzaniu sensorycznym82. Niedawne badania wykorzystujące DTI do identyfikacji uszkodzeń szlaków istoty białej dostarczają wstępnych dowodów na istnienie zaburzeń przetwarzania sensorycznego (SPD) i ich wpływ na zdolności funkcjonalne u dzieci z porażeniem mózgowym83.

Wzór przetwarzania sensorycznego, który dominował u dzieci z porażeniem mózgowym, to problemy z rejestracją lub postawa obserwatora, co sugeruje, że dzieci z porażeniem mózgowym mają wysoki próg bodźców środowiskowych i reagują biernie84. Przetwarzanie przedsionkowe i proprioceptywne to głównie dotknięte domeny przetwarzania sensorycznego85.

Padaczka w porażeniu mózgowym

Leczenie padaczki u dzieci z porażeniem mózgowym często stanowi ogromne wyzwanie terapeutyczne86. Skuteczność farmakologicznego leczenia padaczki w grupie dzieci z porażeniem mózgowym jest niższa niż w grupie dzieci z izolowaną padaczką87.

Wnioski i przyszłe kierunki

Zrozumienie patogenezy porażenia mózgowego jest kluczem do opracowania skutecznych strategii zapobiegawczych i terapeutycznych88. Obecna wiedza na temat patogenezy porażenia mózgowego otwiera możliwość wczesnej diagnozy i rozwoju nowych metod leczenia, zarówno terapeutycznych, jak i zapobiegawczych89.

Pogląd, że leukomalacja okołokomorowa nie jest zjawiskiem statycznym, ale rozwijającym się procesem, zachęca do optymizmu co do możliwości jej korekcji9091. Dalsze badania zmian układów nerwowego i odpornościowego w porażeniu mózgowym przyczynią się do tworzenia fundamentalnie nowych kierunków specyficznej terapii i indywidualnych schematów rehabilitacji9293.

Wciąż istnieje potrzeba dalszych badań nad patofizjologią porażenia mózgowego, szczególnie w celu zrozumienia związku między pierwotnym uszkodzeniem neurologicznym a wtórnymi zmianami w układzie mięśniowym i sensorycznym. Odkrycie neurologicznego lub nerwowo-mięśniowego poprzednika tych miopatii stanowiłoby ogromny krok naprzód w zrozumieniu i leczeniu spastycznego porażenia mózgowego94.

    Cerebral palsy is a group of permanent disorders affecting the development of movement and causing a limitation of activity. Non-progressive disturbances that manifest in the developing fetal or infant brain can lead to cerebral palsy; this is the most common cause of childhood disability. The degree and type of motor impairment and functional capabilities vary depending on the etiology. […] Abnormal development or damage to the fetal or infants brain causes cerebral palsy. The brain insult/injury causing cerebral palsy is non-progressive (eg, static) and can occur in the prenatal, perinatal, or postnatal periods. The etiology of an individual patient is often multifactorial. […] The multifactorial etiology relates to prenatal, perinatal, or postnatal causes. […] Prematurity is a significant risk factor for cerebral palsy. Complications of prematurity that can cause cerebral palsy include: Periventricular leukomalacia, Intraventricular hemorrhage, Periventricular infarcts.

[…] Cerebral palsy is not a disease entity in the traditional sense but a clinical description of children who share features of a non-progressive brain injury or lesion acquired during the antenatal, perinatal or early postnatal period. […] The clinical manifestations of cerebral palsy vary greatly in the type of movement disorder, the degree of functional ability and limitation and the affected parts of the body. […] There is currently no cure, but progress is being made in both the prevention and the amelioration of the brain injury. […] For example, administration of magnesium sulfate during premature labour and cooling of high-risk infants can reduce the rate and severity of cerebral palsy.

    The accurate identification of the actual causes (aetiology) of cerebral palsy (CP) and understanding the causal pathways and the neuropathological correlations are critical to the development of both prevention strategies and a holistic classification of CP. […] The aetiology of CP is multifactorial with diverse and complex causal mechanisms. […] It is obvious that CP is not a single disorder/disease but a group of aetiologically heterogeneous disorders. This implies the aetiology is multifactorial and the causal mechanisms multiple and complex. […] Thus, various aetiological/risk factors act through multiple pathways to damage the developing motor system resulting in variable phenotypes (clinical subtypes of CP) that have common denominators: abnormal pattern of posture and/or movement and presence of accompanying impairments.

    This damage can happen at different times, including before, during and after birth. Damage before birth makes up about 80% of the causes. After birth, it makes up about 10% of causes. […] Examples of the causes include: Preterm (premature) birth. Congenital malformations due to disruptions in fetal brain development. Infections in the central nervous system (brain or spinal cord). Strokes that affect the developing brain. Genetic issues affecting fetal development. Lack of blood flow or oxygen to the fetal brain. Kernicterus (brain damage from toxic buildup of bilirubin, a chemical made in your liver). Meconium aspiration. Newborn hypoglycemia. […] Cerebral palsy often happens simultaneously with other conditions that affect brain function. These other conditions may happen because of the same damage that caused CP.

[…] Risk factors include preterm birth, being a twin, certain infections or exposure to methylmercury during pregnancy, a difficult delivery, and head trauma during the first few years of life. […] New studies suggest that inherited genetic causes play a role in 25% of cases, where formerly it was believed that 2% of cases were genetically determined. […] Some causes of CP are preventable through immunization of the mother, and efforts to prevent head injuries in children such as improved safety. […] There is no known cure for CP, but supportive treatments, medication and surgery may help individuals.

    Other risk factors associated with cerebral palsy are multiple gestation, intrauterine growth restriction, maternal substance abuse, preeclampsia, chorioamnionitis, abnormal placental pathology, meconium aspiration, perinatal hypoglycemia, and genetic susceptibility. […] Prenatal events cause approximately 80% of cerebral palsy cases, and postnatal events cause about 10% of cases. […] Cerebral palsy is a clinical diagnosis based on information gathered from the patients history and physical exam. […] The clinical history should focus on identifying risk factors and likely etiologies of the patients cerebral palsy. […] The physical exam should focus on identifying clinical signs of cerebral palsy. […] Clinical signs and symptoms of cerebral palsy can include micro- or macrocephaly, excessive irritability or diminished interaction, hyper- or hypotonia, spasticity, dystonia, muscle weakness, the persistence of primitive reflexes, abnormal or absent postural reflexes, incoordination, and hyperreflexia.

    Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. […] Most often, the problems occur during pregnancy, but may occur during childbirth or shortly afterwards. […] Risk factors include preterm birth, being a twin, certain infections or exposure to methylmercury during pregnancy, a difficult delivery, and head trauma during the first few years of life. […] New studies suggest that inherited genetic causes play a role in 25% of cases, where formerly it was believed that 2% of cases were genetically determined. […] Some causes of CP are preventable through immunization of the mother, and efforts to prevent head injuries in children such as improved safety. […] There is no known cure for CP, but supportive treatments, medication and surgery may help individuals.

    Cerebral palsy refers to a group of nonprogressive conditions characterized by impairments in muscle tone, voluntary movement, and/or posture, likely resulting from prenatal developmental malformations or perinatal or postnatal central nervous system damage. […] The etiology of cerebral palsy is multifactorial, and a specific cause is sometimes hard to establish. Risk factors that often contribute include prematurity and the disorders it is often associated with, such as in utero disorders, neonatal encephalopathy, and/or chronic bilirubin encephalopathy (formerly known as kernicterus). Perinatal factors (eg, perinatal asphyxia, stroke, central nervous system [CNS] infections) cause a significant minority of cases. […] Abnormal whole exome sequencing or whole genome sequencing results can be seen in more than 30% of patients with CP.

    Cerebral palsy is caused by irregular brain development or damage to the developing brain. This usually happens before a child is born, but it can occur at birth or in early infancy. Often the cause isn’t known. Many factors can lead to changes in brain development. Some include: […] The brain condition causing cerebral palsy doesn’t change with time. Symptoms usually don’t worsen with age. However, as the child gets older, some symptoms might become more or less clear. And muscle shortening and muscle rigidity can worsen if not treated aggressively.

    Potential treatments are being examined, including stem cell therapy. […] However, more research is required to determine if it is effective and safe. […] Cerebral palsy is due to abnormal development or damage occurring to the developing brain. […] This damage can occur during pregnancy, delivery, the first month of life, or less commonly in early childhood. […] Structural problems in the brain are seen in 80% of cases, most commonly within the white matter. […] More than three-quarters of cases are believed to result from issues that occur during pregnancy. […] While in certain cases there is no identifiable cause, typical causes include problems in intrauterine development (e.g. exposure to radiation, infection, fetal growth restriction), hypoxia of the brain (thrombotic events, placental insufficiency, umbilical cord prolapse), birth trauma during labor and delivery, and complications around birth or during childhood.

    Beyond this, the link between the neural insult and the cellular myopathies of cerebral palsy is unclear, but there may be a central mechanism describing how cellular muscular components are altered by the neural lesion in CP. […] These pathological changes are linked to reduced regenerative potential and have been correlated with changes in pro-inflammatory cytokines, satellite cell concentration, and fibroblast activity, all of which are important for achieving muscle homeostasis following mechanical damage to muscle. […] Aberrant changes in levels of cytokines have far-reaching effects on the whole muscle as a result of altered regeneration. […] Elevated levels of pro-inflammatory cytokines interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-) have been found in muscles from individuals with CP and are linked to reductions in protein synthesis, stunted growth, and muscle atrophy. […] The decrease in both concentration and efficacy of SCs contributes to a diminished regenerative potential in the muscle environment in CP.

    Cerebral palsy (CP), a common neurological disorder in children, remains a significant research focus. […] The interleukin (IL) family, pivotal mediators in inflammatory responses, shows increased expression in various neuroinflammatory diseases, markedly influencing their onset and progression. […] Elevated IL levels in the brains of children with CP, in contrast to healthy peers, reflect similar elevations in neurological conditions linked to CP, indicating a strong association between CP and the IL family. […] Anti-inflammatory therapies, particularly those targeting ILs, have shown effectiveness in animal models, diverging from traditional CP management methods. […] This shift suggests IL modulation as a promising therapeutic strategy in pediatric CP. […] This review consolidates recent findings on the IL family’s role in CP, illuminating their evolving relationship.

    Cerebral palsy is the most common cause of childhood-onset, lifelong physical disability in most countries, affecting about 1 in 500 neonates with an estimated prevalence of 17 million people worldwide. […] Cerebral palsy is not a disease entity in the traditional sense but a clinical description of children who share features of a non-progressive brain injury or lesion acquired during the antenatal, perinatal or early postnatal period. […] The clinical manifestations of cerebral palsy vary greatly in the type of movement disorder, the degree of functional ability and limitation and the affected parts of the body. […] There is currently no cure, but progress is being made in both the prevention and the amelioration of the brain injury. […] For example, administration of magnesium sulfate during premature labour and cooling of high-risk infants can reduce the rate and severity of cerebral palsy.

    Moreover they act on an immature brain and could alter the remarkable series of developmental events. […] Biochemical key factors originating in cell death or cell process loss, observed in hypoxic-ischemic as well as inflammatory conditions, are excessive production of proinflammatory cytokines, oxidative stress, maternal growth factor deprivation, extracellular matrix modifications, and excessive release of glutamate, triggering the excitotoxic cascade. […] Only two strategies have succeeded in decreasing CP in 2-year-old children: hypothermia in full-term newborns with moderate neonatal encephalopathy and administration of magnesium sulfate to mothers in preterm labor.

    Potential treatments are being examined, including stem cell therapy. […] However, more research is required to determine if it is effective and safe. […] Cerebral palsy is due to abnormal development or damage occurring to the developing brain. […] This damage can occur during pregnancy, delivery, the first month of life, or less commonly in early childhood. […] Structural problems in the brain are seen in 80% of cases, most commonly within the white matter. […] More than three-quarters of cases are believed to result from issues that occur during pregnancy. […] While in certain cases there is no identifiable cause, typical causes include problems in intrauterine development (e.g. exposure to radiation, infection, fetal growth restriction), hypoxia of the brain (thrombotic events, placental insufficiency, umbilical cord prolapse), birth trauma during labor and delivery, and complications around birth or during childhood.

    The accurate identification of the specific disturbance or specific timing of the event or process that damaged the developing motor system has remained difficult since most (about 75%) of the events occur in the antenatal (prenatal) period. […] However, neuroimaging has made significant contribution to the understanding of the aetiology and pathology of CP and timing of insults. […] Certain risk factors are associated with CP and have been identified in numerous earlier studies in different parts of the world. […] This gave birth to the concept of causal pathways or mechanisms in CP causation and in disorders without a single definitive cause. […] A causal pathway refers to a sequence of interdependent events that culminate in disease.

    The significance of identifying and understanding all these complex causal pathways is in formulating preventive strategies as earlier mentioned. […] The aetiology of CP is attributed to the interaction of multiple risk factors which through complex causal pathways within a limited duration disrupt brain development or augment the risk of damage to the motor system in the foetal/infant brain. […] A link between neuropathology and the clinical-neurological features of CP (neuromuscular deficits, accompanying impairments, severity/functional level, clinical types) exists. However, limitations currently remain in devising a comprehensive neuropathologic classification of CP due to inconsistent structure-function correlations and difficulties in estimating timing of insults.

It can be used to create two- and three-dimensional colour maps of normal white matter architecture and to provide more precise identification of white matter dysgenesis and injury than conventional imaging. […] DTI metrics (lower fractional anisotropy and higher transverse diffusivity) in the descending pyramidal tracts correlate with more significant motor impairment. […] The treatment of epilepsy in children with cerebral palsy is frequently a huge therapeutic challenge. The effectiveness of pharmacological treatment of epilepsy in the group of children with cerebral palsy is lower than in the group of children with isolated epilepsy.

    Cerebral palsy: new pathogenetic concepts […] OBJECTIVE. To review the current knowledge pertaining to the new pathogenetic aspects of cerebral palsy (CP). […] CP is a group of static, heterogeneous clinical syndromes, characterized by abnormal postural mechanisms and motor activities. […] Recently, the elevation of certain coagulation factors (i.e., Leiden factor V mutation) and cytokines (i.e. interleukins, a tumor necrosis factor) and interferons have been related to CP pathogenesis. […] PVL pathogenesis is complex and includes a series of mechanisms that interact among them: fetal/maternal infection, immuneinflammatory reaction, prematurity, intraventricular hemorrhage/iron, ischemia/reperfusion, free radical production, maturational sensitivity of oligodendrocytes, and glutamate effect. […] Current knowledge about CP pathogenesis opens the possibility of early diagnosis and development of new treatments, both therapeutic and preventive.

    The cerebral palsy is highly actual issue of pediatrics, causing significant neurological disability. […] the pathogenesis of cerebral palsy is still poorly understood. […] we reviewed available experimental and clinical data concerning the role of immunocompetent cells in pathogenesis of cerebral palsy. […] The reviewed data demonstrate involvement of immune regulatory cells in the formation of nervous tissue imbalance and chronicity of inborn brain damage. […] The supported opinion, that periventricular leukomalacia is not a static phenomenon, but developing process, encourages us optimism about possibility of its correction. […] The further study of changes of the nervous and immune systems in cerebral palsy will contribute to creating fundamentally new directions of the specific therapy and individual schemes of rehabilitation.

    Beyond this, the link between the neural insult and the cellular myopathies of cerebral palsy is unclear, but there may be a central mechanism describing how cellular muscular components are altered by the neural lesion in CP. […] These pathological changes are linked to reduced regenerative potential and have been correlated with changes in pro-inflammatory cytokines, satellite cell concentration, and fibroblast activity, all of which are important for achieving muscle homeostasis following mechanical damage to muscle. […] Aberrant changes in levels of cytokines have far-reaching effects on the whole muscle as a result of altered regeneration. […] Elevated levels of pro-inflammatory cytokines interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-) have been found in muscles from individuals with CP and are linked to reductions in protein synthesis, stunted growth, and muscle atrophy. […] The decrease in both concentration and efficacy of SCs contributes to a diminished regenerative potential in the muscle environment in CP. […] The elucidation of a neural or neuromuscular antecedent of these myopathies would represent a huge leap forward in understanding and treating spastic CP.
