Recognition of cognitive impairment in schizophrenia

It’s good to see some progress being made towards the recognition of cognitive impairment in schizophrenia and looking at possible treatment options:

Cognitive symptoms, which may include deficits in memory, attention, working memory, processing speed, and problem solving

  • Can be present prior to the onset of illness
  • Persist during periods of psychotic symptom remission
  • Are highly predictive of outcome and functioning

Despite the availability of effective antipsychotic therapy, cognitive impairment remains an important unmet treatment need

Proposed Mechanisms of Cognitive Impairment in Schizophrenia

Conversations on Cognition

Interventions:

  • Cognitive remediation
  • The MATRICS team identified drug mechanisms of interest, including cholinergic, dopaminergic, and glutamatergic approaches
  • Of the cholinergic approaches, the α7 was identified as a top target of investigation

Potential Mechanistic Targets for Treatment of Cognitive Impairment in Schizophrenia

CHOLINERGIC
  • α7 receptor
  • muscarinic M1 MAChR
DOPAMINERGIC
  • dopamine D1 receptor
GLUTAMATERGIC
  • AMPA glutamatergic receptor
  • NMDA glutamatergic receptor
  • Metabotropic glutamate receptor
  • Glycine reuptake
OTHER
  • α2 adrenergic receptor
  • GABAA R subtype
