Cholinergic Functioning, Cognition, and Anticholinergic Medication Burden in Schizophrenia

Area of Science:

• Neuroscience
• Psychiatry
• Pharmacology

Background:

• Acetylcholine (ACh) signaling is crucial for central nervous system function.
• Abnormalities in ACh signaling are implicated in schizophrenia (SZ), a disorder characterized by persistent cognitive deficits.
• Cognitive impairments in SZ remain a significant challenge despite current treatments.

Approach:

• This review synthesizes clinical evidence connecting ACh abnormalities to cognitive deficits in SZ.
• It overviews pro-cognitive strategies targeting the ACh system in SZ.
• The review surveys recent studies on the effects of anticholinergic medication on cognitive outcomes in SZ.

Key Points:

• Clinical evidence links ACh dysfunction to cognitive deficits in schizophrenia.
• ACh-based strategies show potential for improving cognition in SZ.
• Anticholinergic medication burden can negatively impact cognitive function in SZ patients.

Conclusions:

• Understanding ACh's role is critical for addressing cognitive deficits in schizophrenia.
• Further research into ACh-modulating therapies is warranted.
• Careful consideration of anticholinergic burden is necessary for managing SZ patients.
