PSYCHIATRIC AND NEUROLOGICAL DISORDERS

Findings related to psychiatric and neurological disorders and biological processes

Allergies and Dissociative Identity Disorder

Physiological processes coordinate with changing identities, as people with dissociative identity disorder can have allergic reactions while experiencing one identity and no allergies when alternating to another identity.

Diet and Depression

Mediterranean diet is associated with reduced risk of depression.

Social Support and PTSD

Social support protects people from developing PTSD after a traumatic event. Conversely, having PTSD predicts decreases in social support.

Anxiety and Stress-Related Psychopathology

A high anxiety personality trait is a major risk factor to develop stress-related psychopathologies, particularly depression.

Parkinson's and the Placebo Effect

In Parkinson's patients injected with a saline solution, single neurons fired more slowly, just as they would in response to the actual medication.

Loneliness and Dementia

Older adults who report feeling lonely are more likely to develop dementia.
