[Dementia in amyotrophic lateral sclerosis].

New clinical findings suggest a connection between Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD). The two diseases are often seen simultaneously, which complicates the course of the disease for the ALS-patient and the relatives. This paper illustrates this problem and describes a way to monitor the ALS-patient's cognitive and personal changes in an effort to improve his or her rehabilitation and palliation.
