Nervous Trembling: Causes and Types of Involuntary Movements
Nervous tremors can manifest themselves in various forms, from mild trembling of the hands to more serious problems with coordination of movements. These phenomena can be caused by different reasons, but a common feature for all of them is a malfunction in the system that controls the muscular system.
One of the most common types of nervous tremors is tremor. It is characterized by rhythmic, repetitive shaking movements that may occur in the limbs, head, torso, or vocal cords. This type of trembling can be caused by various reasons, including heredity, age-related changes, diseases of the nervous system, stress and fatigue.
One type of tremor is essential tremor, which usually begins between the ages of 40 and 60 and is characterized by shaking of the hands when performing fine movements, such as writing. This type of tremors can progress over time and become more noticeable and limiting daily activities.
Another type of nervous tremor is myoclonus. It is characterized by a momentary contraction of muscles or muscle groups that can occur at any time, both while awake and during sleep. Night shuddering when falling asleep, hiccups and some forms of epilepsy can be manifestations of myoclonus.
Another common type of nervous tremors are tics. Tics are short, sharp and usually repeated jerks of the head, trunk, facial muscles, arms or legs. They can range from simple tics, such as involuntary blinking or forehead furrowing, to complex tics, such as unexplained hand movements or vocal cries. Tics can be caused by stress, fatigue, nervous tension, or brain problems.
To treat nervous tremors, it is important to determine its cause. While some types of tremors may be caused by heredity or age, others may be caused by diseases of the nervous system such as Parkinson's disease or epilepsy. Treatment may include medications, physical therapy, psychotherapy, or surgical correction.
Nervous tremors can be not only an unpleasant and limiting phenomenon, but also a useful reflex. For example, if your hands shake, an image stabilization effect may occur when shooting photos or videos, since the shaking compensates for the movement of your hands. Also, some types of nervous tremors can be symptoms of diseases that can be dangerous to health, so it is important to consult a doctor if you notice involuntary movements.
