Effects on motor activity:
The Limbic system in the brain is affected
Several brain circuits appear to contribute to appetite and food consumption regulation including the hypothalamus, the ventral (limbic) neurocircuit and the dorsal neurocircuit.
- In Anorexia Nervosa, the reward system and the release of dopamine is higher than in the brain of a healthy-weight woman. The release of dopamine has been tied to addiction and this explain how people with anorexia nervosa get addicted to their new life style.
Neurology of the brain with an eating disorder:
People who are diagnosed with Anorexia nervosa and also tend to have restrictive behaviors have shown negative damage done to their nervous system (which is the brain and nerves). Such damages could include:
People who are diagnosed with Anorexia nervosa and also tend to have restrictive behaviors have shown negative damage done to their nervous system (which is the brain and nerves). Such damages could include:
- Disruption of a transmitter
- Neurological symptoms in early adulthood
- During anorexic states, the brain goes through abnormal deformation and structure building.
- Decreased heart rate which means less oxygen for the brain.
- Seizures, numbness of hands or feet.
- A weakened response in the brain regions that are part of the reward circuitry
- A shrinking in the overall size of the brain, including both gray and white matter
- Emotional centers of the brain that leads to depression, irritability, and isolation
- Difficulty thinking, switching tasks, and setting priorities
