Amyotrophic lateral sclerosis with dementia: case report Esclerose lateral amiotrófica com demência: relato de caso

A patient is described in whom a profound and rapidly progressive dementia occurred in association with clinical features of amyotrophic lateral sclerosis. A magnetic resonance imaging showed signs of frontal and especially left temporal atrophy. The pattern of dementia indicated impaired frontotemporal lobe functions, evidenced by reduced tracer uptake in the frontotemporal lobes on brain single photon emission computed tomography. Neuropathological examination in this patient revealed mild frontotemporal atrophy with spongiform changes and neuronal loss affecting mainly layers II and III of the frontotemporal cortices. There was atrophy of the hypoglossal nuclei. The spinal cord changes were consistent with motor neuron disease. The patient showed an irreversible and progressive course. A review of the relevant literature was made.<br>Demência de evolução rápida e progressiva associada com esclerose lateral amiotrófica ocorreu em uma paciente de 68 anos. A ressonância magnética mostrou sinais de atrofia frontal e, principalmente, temporal bilateral mais acentuada à esquerda. A demência se caracterizou como de tipo fronto-temporal, como sugere por hipoperfusão moderada nos lobos fronto-temporais através da tomografia cerebral computadorizada por emissão de fóton simples. O exame neuropatológico revelou atrofia leve fronto-temporal com alterações esponjiformes e perda neuronal afetando principalmente as camadas II e III dos córtices fronto-temporais. Havia importante perda de neurônios em ambos os núcleos do hipoglosso. A medula espinhal mostrou alterações consistentes com doença do neurônio motor. O caso teve curso de quatro anos até o óbito.
