Abstract

Methods of treating cognitive impairment, and/or reducing or preventing one or more neuropsychiatric morbidities in a subject with a neurodegenerative disease or disorder are disclosed. The methods can include administering the subject an effective amount of a (1-piperidinylalkyl)pyrimidinone derivative, preferably ritanserin, or a pharmaceutically acceptable salt thereof, to increase slow wave sleep; to increase dopamine signaling, preferably in the brain, more preferably in the prefrontal cortex; to increase the expression of BDNF preferably in the brain, more preferably in the hippocampus; or a combination thereof. Typically, the compound is administered in a pharmaceutical composition including a pharmaceutically acceptable carrier or excipient. In some embodiments, the subject has not been clinically diagnosed with neurodegenerative disease based on physical symptoms.
