Seizures: Fits/Seizure is a sudden rush of electrical activity in the brain. It is of two types: Generalized seizure (affects the entire brain) and Partial seizures (affects one part of the brain). A mild seizure might be difficult to recognize as it lasts for only a few seconds, during which one lacks awareness. Stronger seizures cause uncontrollable muscle twitches and spasms, lasting for a few seconds to several minutes. Lack of sleep, high fever, stress, bright lights, caffeine, certain medicines, alcohol, and skipping meals/overeating are a few of the most common triggers for seizures.
Panic disorder: Panic disorder is an anxiety disorder characterised by frequent episodes of panic or dread. At times, everyone feels sensations of anxiety and panic. It is a natural reaction to stressful or potentially harmful conditions. However, someone suffering from panic disorder experiences worries, stress, and panic on a regular basis and at any moment, frequently for no apparent cause.
Involuntary muscle spasm: When the nerve impulses that control muscle movements are damaged or interrupted, it could lead to muscle spasms. The sudden involuntary contractions of the muscle can be painful and uncomfortable. Symptoms include muscle tightness, joint stiffness, unusual posture, difficulty in movement, and pain in affected muscles and joints. Fatigue (weakness), stress, extreme heat or cold, infection and tight clothing can trigger muscle spasms.
Restless leg syndrome: Restless leg syndrome, also known as Willis-Ekbom illness, is a common nervous system disorder characterised by an intense, irresistible urge to move the legs. The primary symptom of restless leg syndrome is a strong need to move the legs. It can also induce a creeping or crawling sensation in the feet, calves, and thighs. The sensation is frequently exacerbated in the evening or at night. The arms are occasionally affected as well.
