Uraz głowy i wstrząśnienie mózgu
Rokowania, prognozy i postęp choroby

Prognozowanie wyników leczenia po łagodnym urazie mózgu (mTBI) opiera się na kluczowych predyktorach, takich jak wiek pacjenta, ocena motoryczna oraz reaktywność źrenic przy przyjęciu, z umiarkowaną zdolnością dyskryminacyjną (współczynnik C=0,68-0,70) dla modeli Core i Clinical w skali GOSE. Uwzględnienie wyników tomografii komputerowej i badań laboratoryjnych poprawia trafność prognoz. Przewlekłe objawy pourazowe (PPCS) występują u 10-20% pacjentów po wstrząśnieniu mózgu i są silnie związane z czynnikami ryzyka, takimi jak wcześniejsze zaburzenia psychiczne, wiek powyżej 61 lat, płeć żeńska oraz wysoka częstotliwość korzystania z podstawowej opieki zdrowotnej w roku poprzedzającym uraz. Modele uwzględniające objawy wczesne (2-3 tygodnie po urazie) znacząco zwiększają skuteczność prognostyczną (R² do 37%), co podkreśla znaczenie wczesnej oceny klinicznej i narzędzi takich jak skala TRICORDRR.

Uraz głowy i wstrząśnienie mózgu: Rokowanie (przewidywanie wyników leczenia)

Przewidywanie wyników leczenia po urazie głowy i wstrząśnieniu mózgu stanowi istotne wyzwanie w codziennej praktyce klinicznej. Prognozy dotyczące pacjentów po łagodnym urazie mózgu (mTBI) są kluczowe zarówno dla personelu medycznego, jak i dla samych pacjentów. Znacząca część osób po mTBI nie osiąga pełnego powrotu do zdrowia według Rozszerzonej Skali Wyników Glasgow (GOSE) lub doświadcza przewlekłych objawów pourazowyh (PPCS). Dokładne modele prognostyczne umożliwiają lepsze planowanie terapii i zarządzanie oczekiwaniami pacjentów.12

Modele prognostyczne dla oceny wyników leczenia

Badania nad modelami prognostycznymi dla pacjentów po urazie głowy wykazały, że największa ilość informacji prognostycznych zawarta jest w trzech głównych predyktorach: wieku pacjenta, ocenie motorycznej oraz reaktywności źrenic przy przyjęciu. Modele te wykazują umiarkowaną zdolność dyskryminacyjną między pacjentami z dobrymi i złymi wynikami leczenia po 6 miesiącach, szczególnie jeśli uwzględniają wyniki tomografii komputerowej i badań laboratoryjnych, oprócz tradycyjnych czynników predykcyjnych.3

Bardziej zaawansowane modele Core i Clinical dla skali GOSE charakteryzują się umiarkowaną zdolnością predykcyjną (współczynnik C=0,68-0,70), przy czym stopień ciężkości urazu pozostaje najsilniejszym predyktorem. Natomiast modele przewidujące utrzymywanie się objawów po wstrząśnieniu mózgu (mierzone kwestionariuszem RPQ) wykazują niższą skuteczność (R²=4-9%), która znacząco wzrasta (do R²=12%) po uwzględnieniu wczesnych objawów.4

Czynniki ryzyka przewlekłych objawów pourazowych (PPCS)

Przewlekłe objawy pourazowe (PPCS), określane również jako zespół powstrząśnieniowy, występują u około 10-20% osób po wstrząśnieniu mózgu, gdy objawy utrzymują się dłużej niż oczekiwano po urazie. PPCS może znacząco wpływać na jakość życia pacjenta, w tym zdolność do uczestniczenia w codziennych czynnościach, nauce lub pracy.56

Badania wykazały, że istotnymi czynnikami ryzyka rozwoju PPCS są:78

  • Wcześniejsze zaburzenia psychiczne i zdrowia psychicznego (szczególnie depresja, lęk, zaburzenia dwubiegunowe i zaburzenia osobowości)
  • Wysoka częstotliwość korzystania z podstawowej opieki zdrowotnej w roku poprzedzającym uraz
  • Wiek (osoby starsze powyżej 61 lat są bardziej narażone)
  • Płeć żeńska – kobiety częściej otrzymują diagnozę PPCS niż mężczyźni
  • Historia wcześniejszych urazów głowy lub wielokrotne wstrząśnienia mózgu (choć wyniki badań w tym zakresie są niejednoznaczne)

910

Wysoka częstotliwość korzystania z podstawowej opieki zdrowotnej w roku poprzedzającym uraz jako predyktor przedłużających się objawów jest nowym odkryciem w przypadku wstrząśnienia mózgu, chociaż podobne zależności zaobserwowano w innych schorzeniach, np. bólu kręgosłupa. Również zwiększone ryzyko PPCS u osób starszych stanowi potencjalnie nowe odkrycie, gdyż osoby starsze rzadko są uwzględniane w badaniach nad wstrząśnieniem mózgu.11

Znaczenie wczesnej oceny objawów

Badania pokazują, że ocena objawów we wczesnym okresie po urazie (2-3 tygodnie) znacząco poprawia zdolność przewidywania zarówno wyników w skali GOSE, jak i wystąpienia PPCS. Model kliniczny uwzględniający objawy występujące 2-3 tygodnie po urazie wykazuje znacznie lepszą skuteczność prognostyczną (R²=37% w porównaniu do R²=6% w modelu bez tych danych).12

Narzędzia takie jak skala TRICORDRR (Toronto Rehabilitation Institute Concussion Outcome Determination and Rehab Recommendations) pozwalają lekarzom na szybką ocenę ryzyka przedłużonego powrotu do zdrowia, co z kolei umożliwia opracowanie indywidualnych planów leczenia, takich jak zachęcanie do powrotu do ćwiczeń aerobowych, edukacja na temat wstrząśnienia mózgu czy terminowe skierowania na specjalistyczną opiekę psychologiczną.13

Długoterminowe konsekwencje urazów głowy

Kompleksowe badania obejmujące ponad 31 milionów uczestników wykazały, że uraz mózgu (TBI) wiąże się z licznymi niekorzystnymi następstwami zdrowotnymi, zarówno psychicznymi, jak i fizycznymi. Wśród nich, tylko trzy opierały się na dowodach metaanalitycznych o wysokiej lub umiarkowanej jakości: demencja, skłonność do przemocy oraz stwardnienie zanikowe boczne (ALS). Skłonność do przemocy oraz ALS (po ciężkim urazie mózgu) wykazały znaczące 95% przedziały predykcyjne, sugerując, że w większości populacji pacjentów TBI zwiększa ryzyko wystąpienia tych skutków.14

Osoby po TBI są narażone na szereg niekorzystnych następstw, w tym także te prezentujące łagodny uraz mózgu i wstrząśnienie mózgu. Protokoły wczesnego leczenia potencjalnych długoterminowych problemów są niezbędne, aby zapewnić odpowiednie wsparcie i złagodzić długoterminowe konsekwencje tam, gdzie to możliwe. Czynniki przedurazowe, takie jak nadużywanie substancji psychoaktywnych i schorzenia psychiatryczne, mogą prowadzić do gorszego rokowania.15

Ocena ryzyka wstrząśnienia w warunkach laboratoryjnych

W kontekście badań laboratoryjnych opracowano nowatorską metodę oceny ryzyka wstrząśnienia mózgu – „łączne prawdopodobieństwo wstrząśnienia” (combined probability of concussion), która oblicza ogólne ryzyko wstrząśnienia mózgu na podstawie szczytowych przyspieszeń liniowych i rotacyjnych doświadczanych przez głowę podczas uderzenia. Ta metoda jest wyjątkowa, ponieważ określa prawdopodobieństwo wystąpienia wstrząśnienia mózgu dla danego uderzenia, niezależnie od tego, czy uraz zostałby zgłoszony, czy nie.16

Dla wszystkich analizowanych zestawów danych łączne prawdopodobieństwo wstrząśnienia wykazało największy obszar pod krzywą (AUC), co sugeruje, że był to najlepszy predyktor wstrząśnienia spośród badanych parametrów. Ta metoda może być cennym narzędziem do oceny ryzyka urazu mózgu w warunkach laboratoryjnych w celu oceny bezpieczeństwa produktu, w tym ochrony głowy i projektowania samochodowych systemów zabezpieczeń.17

Czas powrotu do zdrowia

Wstrząśnienia mózgu zwykle trwają kilka tygodni, maksymalnie do miesiąca. Jednak organizmy różnych osób reagują na wstrząśnienia mózgu w odmienny sposób. Niektórzy ludzie naturalnie zdrowieją szybciej, a inni potrzebują więcej czasu. Zazwyczaj nie oznacza to, że dana osoba jest bardziej lub mniej podatna na powikłania.18

Kluczowe jest skonsultowanie się z lekarzem przed powrotem do codziennej rutyny. Nie należy wracać do ćwiczeń, treningów ani uprawiania sportów, dopóki lekarz nie stwierdzi, że jest to bezpieczne. Danie organizmowi czasu potrzebnego na wyleczenie nie oznacza słabości, a przyspieszanie procesu zdrowienia, aby wrócić do treningów czy zawodów, nie świadczy o wyjątkowej wytrzymałości. Mózg będzie się goił we własnym tempie, a jedyną rzeczą, którą można zrobić, aby mu pomóc, jest odpoczynek.19

Znaczenie modeli prognostycznych w praktyce klinicznej

Wczesne przewidywanie wyników leczenia pozwala na ustalenie podstawowego profilu ryzyka dla poszczególnych pacjentów, zapewniając tym samym punkt odniesienia dla oceny jakości świadczonej opieki zdrowotnej. Modele prognostyczne są szczególnie istotne dla bardziej efektywnego projektowania i analizy randomizowanych badań klinicznych (RCT). Proponowane skale mogą również wspierać klinicystów w ich wstępnej ocenie ciężkości urazu i rokowania u pacjenta z TBI.20

Wyniki badania CREST (Concussion Recovery Study) oraz innych podobnych inicjatyw mają na celu zidentyfikowanie zestawu czynników przedurazowych i miar wyników ocenianych podczas wczesnego okresu po urazie, które mogą być wykorzystane do przewidywania, którzy pacjenci są narażeni na ryzyko wystąpienia PPCS w porównaniu z tymi, którzy wracają do zdrowia w typowym czasie.21

Te wieloaspektowe konsekwencje PPCS przyczyniły się do uznania go za pojawiający się problem zdrowia publicznego. PPCS może głęboko wpływać na zdolność danej osoby do wykonywania codziennych czynności i może prowadzić do funkcjonalnych konsekwencji, w tym opóźnionej lub zmniejszonej zdolności do powrotu do pracy, nauki i uprawiania sportu, a także obniżonej satysfakcji i jakości życia.22

Strategie zapobiegania i postępowania

Jedynym sposobem na zmniejszenie ryzyka wystąpienia PPCS jest unikanie urazów głowy. Szereg specjalistów ochrony zdrowia może pomóc w leczeniu przewlekłych objawów pourazowych. Regularne wizyty kontrolne u lekarza podstawowej opieki zdrowotnej pomogą mu monitorować proces powrotu do zdrowia i określić, czy konieczne są jakiekolwiek zmiany w planie leczenia.23

Wnioski z badań wskazują na potencjalne kierunki dla praktyki klinicznej. Protokoły wczesnego leczenia potencjalnych długoterminowych problemów są niezbędne, aby zapewnić osobom z TBI wystarczające wsparcie i złagodzić długoterminowe konsekwencje. W szczególności należy rozważyć ryzyko demencji, skłonności do przemocy i ALS. Podejścia medycyny precyzyjnej do zarządzania TBI mogą pomóc w lepszym rokowaniu wyników i odpowiednim ukierunkowaniu leczenia i innych zasobów opieki zdrowotnej.24

    https://pmc.ncbi.nlm.nih.gov/articles/PMC10458380/
    After mild traumatic brain injury (mTBI), a substantial proportion of individuals do not fully recover on the Glasgow Outcome Scale Extended (GOSE) or experience persistent post-concussion symptoms (PPCS). […] We aimed to develop prognostic models for the GOSE and PPCS at 6 months after mTBI and to assess the prognostic value of different categories of predictors (clinical variables; questionnaires; computed tomography [CT]; blood biomarkers). […] The Core and Clinical models for GOSE showed moderate discrimination (C=0.68 95% confidence interval 0.68 to 0.70 and C=0.70[0.69 to 0.71], respectively) and injury severity was the strongest predictor. […] The performance of models for RPQ was modest (R2=4% Core; R2=9% Clinical), and extensions with early symptoms increased the R2 to 12%. […] In conclusion, the models based on variables available before discharge have moderate performance for the prediction of GOSE and poor performance for the prediction of PPCS.

    https://bmjopen.bmj.com/content/11/5/e046460
    Mild traumatic brain injury (mTBI) is a complex injury with heterogeneous physical, cognitive, emotional and functional outcomes. Many who sustain mTBI recover within 2 weeks of injury; however, approximately 10%–20% of individuals experience mTBI symptoms beyond this typical recovery timeframe, known as persistent post-concussion symptoms (PPCS). […] Despite increasing interest in PPCS, uncertainty remains regarding its prevalence in community-based populations and the extent to which poor recovery may be identified using early predictive markers. […] The ability to predict who will develop PPCS would be of great benefit. From a clinical perspective, a prognostic model would assist with decision-making and management of patient expectations about their recovery. […] It is increasingly recognised that a more fruitful approach would draw from multiple assessment elements for multivariate prognostic modelling to better calibrate the risk of poor clinical outcomes.

    Prognostic models using baseline characteristics provide adequate discrimination between patients with good and poor 6 mo outcomes after TBI, especially if CT and laboratory findings are considered in addition to traditional predictors. […] We aimed to develop prognostic models based on admission characteristics, which would allow application of the model before in-hospital therapeutic interventions. […] The largest amount of prognostic information was contained in a core set of three predictors: age, motor score, and pupillary reactivity at admission. […] Early prediction of outcome permits establishment of a baseline risk profile for individual patients, thus providing a reference for assessing quality of health-care delivery. […] Prognostic models are particularly relevant for a more efficient design and analysis of RCTs. […] The proposed scores may also support clinicians in their initial assessment of the severity and prognosis of a TBI patient. […] In conclusion, prognostic models are now available that provide adequate discrimination between patients with good and poor 6-mo outcome.

    https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003652
    Approximately 10% to 20% of people with concussion experience prolonged post-concussion symptoms (PPCS). […] This study aimed to derive a risk score for PPCS by determining which demographic factors, premorbid health conditions, and healthcare utilization patterns are associated with need for prolonged concussion care among a large cohort of adults with concussion. […] In this study, we observed that premorbid psychiatric conditions, pre-injury health system usage, and older age were associated with increased risk of a prolonged recovery from concussion. This risk score allows clinicians to calculate an individuals risk of requiring treatment more than 6 months post-concussion. […] The goal of the study was to derive a risk score for prolonged post-concussion symptoms (PPCS) among adults with concussion that could enable clinicians treating patients with concussion to determine probable recovery and facilitate appropriate care pathways to improve patient quality of life and recovery.

    Persistent Post-Concussion Symptoms (PPCS) also called post-concussion syndrome- occurs when concussion (mild traumatic brain injury) symptoms last longer than expected after an injury. […] PPCS can have significant impacts on a persons life, including their ability to participate in daily activities, school and/or work. […] Research indicates that the risk of PPCS may change with age, with adolescents and older adults being more likely to experience poor outcome following concussion injury. […] Females are more likely to be diagnosed with PPCS relative to males. […] People with a history of mental health disorders have been found to be more likely to experience PPCS. […] The only way to lower the risk of experiencing PPCS is to avoid head injury in the first place. […] Individuals who experience multiple concussions/repeated head injury may be more likely to experience PPCS, though research findings on this are mixed. […] A range of healthcare professionals can assist with persistent post-concussion symptoms. […] Regular follow-up appointments with your GP will help them monitor your recovery journey and determine if any changes need to be made to your treatment plan.

Older age (over 61 years), premorbid psychiatric and mental health history, and high usage of primary care in the year before injury were associated with greater risk of PPCS. […] The most predictive factors in developing PPCS were a prior diagnosis of mental health problems, especially depression, anxiety, bipolar and personality disorders, high frequency of pre-injury primary healthcare use, and age.

  • #14 An umbrella review of health outcomes following traumatic brain injury | Nature Mental Health
    https://www.nature.com/articles/s44220-024-00356-5
    In this comprehensive umbrella review of 24 mental and physical health outcomes following TBI, we have summarized evidence from more than 31 million participants. Overall, TBI was associated with multiple mental and physical adverse health outcomes. Among these, only three were based on high- or moderate-quality meta-analytic evidence: dementia, violence perpetration, and ALS. Violence perpetration and ALS (following severe TBI) also exhibited significant 95% prediction intervals, suggesting that in most patient populations, TBI increases risk of these outcomes. […] Our findings underscore the need for effective interventions to address risk of longer-term outcomes. Early identification of patients at risk of adverse outcomes is important for guiding optimal management. Enhancing health literacy and awareness through psychoeducation may improve quality of life. For example, increasing awareness of possible violent behavior following brain injuries could lead to risk management, with potential prevention of harms to carers and others. Improved understanding of TBI sequelae can allow for appropriate targeting of health-care resources and implementation of interventions to maintain well-being.

    https://www.nature.com/articles/s44220-024-00356-5
    Taken together, the findings provide some potential directions for clinical practice. Individuals with TBI are at risk of a range of adverse outcomes, including those presenting with mild TBI and concussion. Protocols for early treatment of potential long-term problems are necessary to ensure those with TBI are provided with sufficient support and that long-term consequences are mitigated where possible. The reviews findings demonstrate the complex paths and wide range of outcome domains following head injury. In particular, risks of dementia, violence perpetration, and ALS should be considered. Pre-injury factors such as substance misuse and psychiatric conditions may lead to poor prognosis. Precision medicine approaches to TBI management can assist in better outcome prognosis and appropriate targeting of treatments and other health-care resources.

    Recent research has suggested possible long term effects due to repetitive concussions, highlighting the importance of developing methods to accurately quantify concussion risk. […] The combined probability of concussion is a valuable method to assess concussion risk in a laboratory setting for evaluating product safety. […] This study introduces a new injury metric, the combined probability of concussion, which computes the overall risk of concussion based on the peak linear and rotational accelerations experienced by the head during impact. […] The combined probability of concussion is unique in that it determines the likelihood of sustaining a concussion for a given impact, regardless of whether the injury would be reported or not. […] The predictive capability of this new metric is compared to that of single biomechanical parameters.

    The combined probability of concussion had the greatest area under the curve for all datasets. […] For all datasets, the combined probability of concussion produced the greatest AUC, suggesting it was the best predictor of concussion of the parameters investigated. […] However, linear acceleration was not significantly different than the combined probability of concussion, suggesting it can predict concussion as well as the combined probability of concussion in the datasets analyzed in this study. […] The combined probability of concussion method accounted for this because it considered both linear and rotational accelerations for each impact. […] The combined probability of concussion could be a valuable method to assess brain injury risk in a laboratory setting for evaluating product safety, including head protection and automobile restraint design, considering that the impact characteristics are similar to those analyzed here.

    The Concussion Recovery Study (CREST) is a large, cross-institutional study conducted in Perth, Western Australia (WA), developed with the aim of identifying individuals that are at an increased risk of developing PPCS. […] The study hypothesises that a suite of preinjury factors and outcome measures that are assessed during the early presentation period may be used to predict those at risk of experiencing PPCS compared with those who recover within a typical timeframe. […] The primary objectives of CREST are: (1) To establish a large-scale clinical research dataset of adults experiencing mTBI in Western Australia, in order to observe the typical pattern of recovery from mTBI and determine the incidence of PPCS within the Western Australian context. (2) To identify a suite of preinjury factors and outcome measures during the early presentation period that may be used to predict those at risk of experiencing PPCS compared with those who recover within a typical timeframe.

    A plethora of studies have been conducted assessing biomarkers and other factors for their capacity to predict outcome following mTBI. […] The multitudes of documented ramifications stemming from PPCS have contributed to its status as an emergent public health issue. PPCS may profoundly impact an individual’s ability to carry out activities of daily living, and can result in functional consequences including delayed or reduced ability to return to work, study and playing sport, as well as impaired satisfaction and quality of life.

    Persistent Post-Concussion Symptoms (PPCS) also called post-concussion syndrome- occurs when concussion (mild traumatic brain injury) symptoms last longer than expected after an injury. […] PPCS can have significant impacts on a persons life, including their ability to participate in daily activities, school and/or work. […] Research indicates that the risk of PPCS may change with age, with adolescents and older adults being more likely to experience poor outcome following concussion injury. […] Females are more likely to be diagnosed with PPCS relative to males. […] People with a history of mental health disorders have been found to be more likely to experience PPCS. […] The only way to lower the risk of experiencing PPCS is to avoid head injury in the first place. […] Individuals who experience multiple concussions/repeated head injury may be more likely to experience PPCS, though research findings on this are mixed. […] A range of healthcare professionals can assist with persistent post-concussion symptoms. […] Regular follow-up appointments with your GP will help them monitor your recovery journey and determine if any changes need to be made to your treatment plan.

    Taken together, the findings provide some potential directions for clinical practice. Individuals with TBI are at risk of a range of adverse outcomes, including those presenting with mild TBI and concussion. Protocols for early treatment of potential long-term problems are necessary to ensure those with TBI are provided with sufficient support and that long-term consequences are mitigated where possible. The reviews findings demonstrate the complex paths and wide range of outcome domains following head injury. In particular, risks of dementia, violence perpetration, and ALS should be considered. Pre-injury factors such as substance misuse and psychiatric conditions may lead to poor prognosis. Precision medicine approaches to TBI management can assist in better outcome prognosis and appropriate targeting of treatments and other health-care resources.
