Your friend's symptoms of inability to concentrate, irritability, and insomnia suggest that she may have insomnia, which is a sleep disorder characterized by difficulty falling asleep or staying asleep. Dementia is a neurological disorder that affects memory, thinking, and behavior. Melatonin is a hormone produced by the pineal gland that regulates sleep-wake cycles. Paradoxical sleep refers to the stage of sleep when the body is physically inactive, but the brain is highly active and dreaming occurs.
