Physical disorders and causes of death in relatives of Alzheimer's disease patients.
Genetic risk factors are important in Alzheimer's disease (AD). These risk factors might also predispose for other disorders. This might lead to a familial coaggregation of AD and other disorders, e.g. Down's syndrome or Parkinson's disease. In the present study the risk of physical disorders in relatives of AD patients, of depressed patients and of control subjects were compared. ⋯ The results do not support a major overlap between the genetic risk of AD and the genetic risk of cerebrovascular disease, Down's syndrome, haematological malignancies or Parkinson's disease. The finding of an increased risk of congenital malformations in relatives of AD patients needs further replication before it can be stated. The increased risk of dementia or depression with cognitive impairment in elderly relatives of patients with AD or MD increases the risk of accidents like falls. The genetic risk of depression in relatives of patients with MD could have a negative influence on the prognosis of peptic ulcera.
