Chronic stress results from demands that persist, such as financial insecurity, unsafe housing, discrimination or ongoing conflict. Repeated strain can affect sleep, physical health and the capacity to manage everyday tasks. In schizophrenia, these pressures…Continue Reading
D3 and D4 are members of the D2-like receptor family. They have different distributions and pharmacological properties from D2. D3 is studied in relation to motivation and reward, while D4 has attracted interest partly because…Continue Reading
The stress response involves coordinated activity across the brain, autonomic nervous system and hormonal systems. The hypothalamic–pituitary–adrenal axis helps regulate cortisol, while sympathetic activation contributes to changes in heart rate and alertness. These systems adapt…Continue Reading

Trauma-related conditions and psychosis can share experiences such as heightened threat, unusual perceptions, sleep disturbance and withdrawal. Flashbacks, intrusive memories and dissociation may be confused with hallucinations, while persecutory beliefs may be difficult to distinguish…Continue Reading
