This case study shows that adding donepezil to quetiapine may improve memory in patients with schizophrenia and cognitive impairment. Further research is needed to confirm these findings.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Pharmacology

Background:

  • Schizophrenia is often associated with significant cognitive impairment, particularly affecting memory.
  • Cognitive deficits in schizophrenia can negatively impact daily functioning and quality of life.
  • Current antipsychotic treatments, like quetiapine, may not fully address cognitive symptoms.

Observation:

  • A 54-year-old female patient diagnosed with schizophrenia presented with notable memory dysfunction.
  • The patient was receiving quetiapine for her schizophrenia symptoms.
  • Cognitive assessment revealed significant memory deficits impacting her daily life.

Findings:

  • The addition of donepezil, a cholinesterase inhibitor, to her existing quetiapine regimen was initiated.

  • Following the introduction of donepezil, the patient exhibited noticeable improvement in memory function.
  • Quetiapine dosage remained stable, suggesting donepezil's specific contribution to cognitive enhancement.

    • Implications:

    • This case suggests a potential therapeutic role for donepezil in managing memory impairment in schizophrenia.
    • Further controlled studies are warranted to validate the efficacy and safety of donepezil in this patient population.
    • Investigating the neurobiological mechanisms underlying donepezil's effect on schizophrenia-related cognitive deficits is crucial.
