Mental Disorders As Metabolic Brain Problems
- Mental disorders are fundamentally metabolic problems of the brain that reflect how cells produce and manage energy.
- Brian Johnson cites Chris Palmer's framing: metabolism is converting food to energy, building cells, and clearing waste, which underlies mental health.
Sleep Problems Worsen Many Disorders
- Sleep problems (too much, too little, or poor quality) impose metabolic stress and can worsen or trigger psychiatric and metabolic diseases.
- Brian lists conditions worsened by sleep deprivation including depression, mania, anxiety, dementia, ADHD, schizophrenia, and substance abuse.
Poor Sleep Hurts Metabolic Health
- Poor sleep also aggravates metabolic diseases: it raises blood sugar in diabetes, promotes weight gain in obesity, and increases cardiac risk.
- Brian emphasizes that sleep can both worsen existing illness and contribute to disease onset in healthy people.
