Implication

Does not support clinical use of platelet calcium assays; leaves open mechanistic links between psychiatric illness and cardiovascular disease.

Key Points

To evaluate the evidence supporting platelet intracellular calcium responses to neurotransmitter stimulation as peripheral state or trait markers for psychiatric illnesses and related cardiovascular comorbidities.
Literature review evaluating platelet neurochemical properties and intracellular calcium signaling dynamics in psychiatric disease models.
Assessment of platelet response specificity and selectivity across major depression, mania, schizophrenia, and psychotic depression.
Platelet intracellular calcium responses to neurotransmitter stimulation function as viable state or trait markers in major depressive disorder.
Differential calcium signaling patterns show utility for categorizing psychotic conditions, including schizophrenia and mania, while outlining a shared biological mechanism linking psychiatric disorders to cardiovascular disease.

Intervention

Platelet intracellular calcium response to neurotransmitter stimulation as a peripheral marker

The platelet intracellular calcium response may serve as a useful peripheral marker for psychiatric illnesses and could help explain the link between psychiatric disorders and cardiovascular disease.
