\nSistemul de \u00eenv\u0103\u0163are automat\u0103 a analizat scan\u0103rile cerebrale ale unor persoane cu v\u00e2rste \u00eentre 69 \u015fi 84 de ani. Lotul a inclus 281 de scan\u0103ri cu func\u0163ii mentale normale, 332 cu tulbur\u0103ri cognitive u\u015foare \u015fi 202 cu Alzheimer confirmat, conform The Independent.<\/p>\n
\nAlgoritmul a examinat 95 din cele aproape 200 de regiuni distincte ale creierului. Principalul factor predictiv identificat a fost pierderea de volum cerebral \u00een zone precise. Zonele afectate includ hipocampusul, care formeaz\u0103 memoria, amigdala, care proceseaz\u0103 frica, \u015fi cortexul entorhinal, responsabil de sim\u0163ul timpului. Modific\u0103rile \u00een aceste zone semnaleaz\u0103 debutul bolii.<\/p>\n
\n\u201eAm descoperit c\u0103 tehnologiile de \u00eenv\u0103\u0163are automat\u0103 pot analiza cantit\u0103\u0163i mari de date pentru a identifica schimb\u0103ri subtile”, a explicat Benjamin Nephew, profesor asistent la institut.<\/p>\n
\nCercetarea a relevat c\u0103 boala evolueaz\u0103 diferit \u00een func\u0163ie de sex. La femei, pierderea de volum cerebral apare \u00een cortexul temporal mijlociu st\u00e2ng, implicat \u00een limbaj \u015fi percep\u0163ie vizual\u0103. La b\u0103rba\u0163i, zona afectat\u0103 este cortexul entorhinal drept.<\/p>\n
\nCercet\u0103torii cred c\u0103 aceste diferen\u0163e sunt legate de modific\u0103rile hormonale. Pierderea de estrogen la femei \u015fi de testosteron la b\u0103rba\u0163i ar putea explica tiparele distincte observate.<\/p>\n
\nDiagnosticarea timpurie ofer\u0103 pacien\u0163ilor \u015fi medicilor timp crucial. Pot fi luate m\u0103suri pentru a \u00eencetini progresia bolii \u00eenainte ca simptomele s\u0103 devin\u0103 severe.<\/p>\n
\n\u201eDiagnosticarea precoce poate fi dificil\u0103, deoarece simptomele se pot confunda cu \u00eemb\u0103tr\u00e2nirea normal\u0103”, a subliniat Nephew. Inteligen\u0163a artificial\u0103 \u00een predic\u0163ia Alzheimer ar putea schimba fundamental aceast\u0103 realitate.<\/p>\n
\nPeste 7,2 milioane de americani sufer\u0103 \u00een prezent de Alzheimer, potrivit Alzheimer’s Association. Cercet\u0103rile continu\u0103 pentru identificarea altor factori predictivi.<\/p>\n
