Psychotropic effects on neurodegeneration, neurogenesis, and behavior.
The effects of quetiapine (QTP), valproate (VPR), lithium (Li), fluoxetine (FLX), donepezil (DNP), and memantine (MMT) are displayed for specific steps in the neuropathic process, derived from preclinical models relevant to Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD) regarding both pre-symptomatic and early clinical stages of these diseases. Therapeutic effects of psychotropic drugs are indicated by blue text on an aqua background while potentially adverse effects are indicated by white text on a red background. Arrowheads signify upregulation, facilitation, or promotion whereas lines ending in perpendicular bars signify downregulation, inhibition, or reduction. Aβ: Amyloid beta; APP: amyloid precursor protein; BDNF: brain derived neurotrophic factor; PS1: presenilin 1; RNS: reactive nitrogen species; ROS: reactive oxygen species.
