Introduction

Dystonia is a movement disorder that is characterized by uncontrollable muscle contractions. The impacted body part twists involuntarily as a result of the shrinkage, likely to result in repetitive motion or unusual postures. Dystonia can affect a single muscle, a group of muscles, or the parts of the body. Dystonia affects approximately 1% of the population, with women being much more susceptible than men. There are various types of dystonia, and dystonia can be caused by a variety of diseases and disorders. Dystonia is categorised based on the clinical features such as early onset, body distribution, nature of symptoms, and related functions such as additional neurological conditions or neurological problems.

Types of dystonia

Generalized: Normal birth history as well as developmental disabilities, Autosomal dominant inheritance, early signs in adolescence It begins in the lower limbs and spreads upwards. Torsion dystonia is also known as idiopathic torsion dystonia (old terminology "dystonia musculorum deformans").

Segmental dystonia: This affect two adjoining parts of the body, hemi-dystonia affects the arm and foot on one side whereas multifocal dystonia affects the different region of the body, generalized dystonia affects to the body and it involves most to legs and back region.

Myoclonic dystonia: is a condition in which some situations are inherited and been linked to a missense mutation in the dopamine-D2 receptor. A few of these cases have reacted favourably to alcohol.

Symptoms

Dystonia symptoms can vary from mild to severe. Dystonia can actually impact body parts, and the signs of dystonia frequently progress in stages. Among the early symptoms are A "leg trying to drag”, Muscle cramps of the foot Involuntary neck pulling, Blinking which is uncontrollable, Difficulties communicating. Stress or fatigue may occur or worsen the condition. Because of the continuous muscular contractions, people with dystonia frequently complain of pain and exhaustion. If dystonia symptoms start in early life, they usually begin in the leg or arm. However, they quickly move on to the rest of the body. However, after adolescence, the rate of progression slows.

Causes

The majority of dystonia case scenarios have no known cause. Dystonia appears to be caused by a malfunction in the basal ganglia. That is the part of the brain that is in charge of causing muscle contractions. The issue is related to how nerve cells interact. Damage to the basal ganglia causes acquired dystonia. The damage could be caused by Brain injury, Stroke Tumor Oxygen deficiency, Infection, Reactions to drugs. Dystonias also can be categorised as syndromes based on the patterns they exhibit Dystonia that tends to affect the eyes is known as blepharospasm. It is usually preceded by uncontrollable blinking. Initially, it usually only affects one eye. However, both eyes are subsequently affected. The spasms cause the eyelids to close involuntarily. They can even cause them to remain closed. The individual may have visual acuity. However, the person becomes functionally blind as a result of the permanent closing of the eyelids. The most commonly used type is cervical dystonia, also known as torticollis. Cervical dystonia is most common in people in their forties and fifties. However, it has been noted in people of all ages. Cervical dystonia occurs when the muscles of the neck, having caused the head to twist and turn or to be pulled backward or forward.
