Common Symptoms Of Neuromuscular Diseases

Muscle Twitches

An individual who frequently experiences muscle twitches may be affected by a neuromuscular disease. Fasciculation or muscle twitches describe when abnormal activities in an individual's nerves cause the muscles to jump or spasm repeatedly over minutes or hours. However, a muscle twitch is an involuntary muscle contraction that is short and repetitive, while a muscle spasm is an involuntary contraction that lasts longer and is known to produce pain. Muscle twitches in patients affected by neuromuscular diseases typically only occur in a small muscle or a small portion of a muscle, rarely producing pain. Most individuals describe muscle twitching to be an irritating or uncomfortable pulsing or vibrating sensation. Muscle spasms are described more as myalgia or cramping of the muscle. The most common parts of the body affected by muscle twitches in patients who have a neuromuscular disease include the shoulders, arms, legs, face, neck, tongue, and hips.

Double Vision

Neuromuscular diseases cause an individual to experience adverse effects on the muscles around their body that move organs and body parts effectively. An individual's vision is dictated by their eyes and the muscles that move them in sync with each other. A healthy individual sees a single object in front of them as a single object because the muscles that move their eyes keep them lined up with each other perfectly so both eyes project a single object into the brain. Neuromuscular diseases can cause muscles around the body to become weak or malfunction. Muscle weakness describes when an individual is unable to produce a muscle contraction even when making the greatest effort to do so. Although the muscles that move an individual's eyes are involuntary, they can experience muscle weakness and muscle spasms that throw the alignment of the eyes off balance. When the eyes do not align together perfectly, the affected individual will experience double vision.
