Abstract
Amyotrophic lateral sclerosis (ALS), frontotemporal degeneration and Parkinson’s disease may be different expressions of the same neurodegenerative disease. However, association between ALS and parkinsonism-dementia complex (ALS-PDC) has only rarely been reported apart from the cluster detected in Guam. We report a patient presenting with ALS-PDC in whom pathological mutations/expansions were investigated. No other family members were reported to have any symptoms of a neurological condition. Our case demonstrates that ALS-PDC can occur as a sporadic disorder, even though the coexistence of the three clinical features in one patient suggests a single underlying genetic cause. It is known that genetic testing should be preferentially offered to patients with ALS who have affected first or second-degree relatives. However, this case illustrates the importance of genetic counseling for family members of patients with sporadic ALC-PDC in order to provide education on the low recurrence risk. Here, we dicuss the ethical, psychological and practical consequences for patients and their relatives.
