Four patients with amyotrophic lateral sclerosis (ALS) and dementia are reported. Mental symptoms antedated motor signs and were investigated with a neuropsychology battery, which brought out different patterns of cognitive impairment. A case presented with frontal dementia, another with a predominant aphasic, apraxic, amnesic syndrome, while the remainders showed cognitive decline in association with blunt affect. Motor signs were characterized by a precocious involvement of the upper motor system.
