Low levels of hypocretin, a brain hormone that encourages awake, are frequently connected to this chronic neurological sleep disorder, which is brought on by a disruption in the regulation of sleep-wake cycles. This is frequently caused by an autoimmune process rather than damage or deterioration. The structure of the brain is unaffected. Lifestyle changes and prescription drugs, such as stimulants or wake-promoting substances as modvigil 200 (https://www.smartfinil.net/product/modvigil-200/), can effectively control symptoms. Most narcoleptics can function normally, continue their occupations, and lead active lives without growing brain damage if they receive the right treatment.
