Sleep disorders
A collective term for various phenomena characterized by the fact that those affected do not get restful sleep. Both psychological and organic causes can contribute to this. Symptoms range from problems falling asleep and staying asleep to undesirable behaviors during sleep such as sleepwalking, restless legs when falling asleep, sleep apnea, etc. According to estimates, up to 30 percent of all adults in Western countries suffer from some form of sleep disorder. Finding the causes is often complicated, and analysis in a sleep laboratory is the best method of investigation.

Alzheimer's disease
Alzheimer's disease is a progressive neurodegenerative disorder characterized by cortical atrophy, nerve cell loss, synapse loss, and deposits of amyloid plaques and neurofibrillary tangles, leading to dementia and loss of function. Early symptoms include memory problems, speech disorders, executive deficits, depressive moods, and subtle personality changes. As the disease progresses, global cognitive impairment, aphasia, agnosia, apraxia, and behavioral abnormalities such as apathy, restlessness, and sleep disorders occur. The disease was first described in 1907 by Alois Alzheimer.
