Estudo aponta novo sintoma precoce do Alzheimer

saúde

Um estudo revela que pessoas com Alzheimer inicial têm dificuldade em percorrer caminhos com curvas, devido a problemas de direção.

saúde

Participantes foram testados em um experimento com óculos de realidade virtual, percorrendo caminhos com diferentes condições.

saúde

Indivíduos com comprometimento cognitivo leve tiveram dificuldades específicas ao fazer curvas, enquanto os saudáveis não.

saúde

A pesquisa sugere que o Alzheimer afeta regiões do cérebro ligadas à navegação espacial, explicando as dificuldades encontradas.

saúde

A doença começa na parte posterior do cérebro, afetando os lobos parietais, fundamentais para a navegação.

saúde

O estudo destaca a importância da habilidade de navegação de caminho, comprometida em estágios iniciais do Alzheimer.

saúde

Os desafios de navegação encontrados foram exclusivos da doença de Alzheimer, evidenciando suas características neurológicas.

saúde

O cérebro das pessoas saudáveis automaticamente atualiza sua localização, enquanto o Alzheimer prejudica essa capacidade.

saúde

Os resultados reforçam a relação entre as dificuldades de navegação e o Alzheimer, destacando áreas afetadas no cérebro.
