ADHD Drugs Linked to Psychotic Symptoms in Children
Stimulant medications like Ritalin and Adderall, often prescribed to treat children diagnosed with ADHD, are known to cause hallucinations and psychotic symptoms.

Researchers from the City College of New York and Columbia University published a study this month testing the hypothesis that people diagnosed with schizophrenia treated long-term with antipsychotic drugs have worse outcomes than patients with no exposure to these drugs. They concluded that there is not a sufficient evidence base for the standard practice of long-term use of antipsychotic medications.
Psychiatrists Overestimate Antidepressants, Underestimate Placebo

The research, published this week in BMJ Open, found the strongest effect for serotonin reuptake inhibitors (SSRIs) and the antidepressant venlafaxine.
Mindfulness Pain Relief Distinct from Placebo Effect
A new study demonstrates that the practice of mindfulness may ease pain in a way that is mechanistically distinct from the placebo effect.
