    This study found that drugs affecting acetylcholine improved cognitive function in patients with psycho-organic syndrome (POS) and dementia. Monitoring cerebrospinal fluid (CSF) acetylcholine levels may help assess dementia severity and treatment effectiveness.

    Area of Science:

    • Neuroscience
    • Gerontology
    • Pharmacology

    Background:

    • Psycho-organic syndrome (POS) and dementia significantly impact cognitive function.
    • Acetylcholine plays a crucial role in cognitive processes.
    • Current treatments aim to modulate neurotransmitter systems, including acetylcholine.

    Purpose of the Study:

    • To investigate the effects of drugs influencing acetylcholine turnover on cognitive function and cerebrospinal fluid (CSF) acetylcholine levels.
    • To compare treatment outcomes in patients with POS versus those with dementia (senile, Alzheimer, multi-infarct).
    • To explore the correlation between CSF acetylcholine variations and cognitive improvements.

    Main Methods:

    • A 30-day treatment study involving 13 POS patients and 10 dementia patients.

  • Administration of drugs known to influence neuronal acetylcholine turnover: Phosphatidylcholine, piracetam, and S-adenosylmethionine.
  • Assessment of CSF acetylcholine levels, reaction times to visual (TRS-V) and auditory (TRS-H) stimuli, and Sandoz Clinical Assessment Geriatric (SCAG) scores.

    • Main Results:

    • POS patients initially had higher CSF acetylcholine, faster reaction times (TRS-V, TRS-H), and lower SCAG scores than dementia patients.
    • During treatment, CSF acetylcholine decreased in POS patients but remained stable in dementia patients.
    • Both groups showed cognitive improvements (shorter TRS-V/TRS-H, lower SCAG scores), with more significant gains in the POS group.
    • CSF acetylcholine fluctuations correlated with cognitive improvements in POS patients.

    Conclusions:

    • Drugs influencing acetylcholine turnover show therapeutic potential for POS and dementia.
    • Monitoring CSF acetylcholine levels may aid in assessing dementia progression and individual treatment response.
    • Further research is warranted to elucidate the precise mechanisms and optimize therapeutic strategies.
