Tropical spastic paraparesis (TSP), is a medical condition that causes weakness, muscle spasms, and sensory disturbance by human T-lymphotropic virus resulting in paraparesis, weakness of the legs. As the name suggests, it is most common in tropical regions , including the Caribbean . [ 4 ]
Other causes of hemiplegia in adults include trauma, bleeding, brain infections and cancers. Individuals who have uncontrolled diabetes, hypertension or those who smoke have a higher chance of developing a stroke. Weakness on one side of the face may occur and may be due to a viral infection, stroke or a cancer. [12]
Its causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis. Muscle weakness can also ...
Myasthenia gravis, or MG, is a chronic autoimmune neuromuscular disorder that causes muscle weakness and fatigue. Myasthenia gravis is one of the rarest and most concerning muscular disorders ...
Flaccid paralysis is a neurological condition characterized by weakness or paralysis and reduced muscle tone without other obvious cause (e.g., trauma). [1] This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles.
Superior alternating hemiplegia (also known as Weber syndrome) has a few distinct symptoms: contralateral hemiparesis of limb and facial muscle accompanied by weakness in one or more muscles that control eye movement on the same side. [2] Another symptom that appears is the loss of eye movement due to damage to the oculomotor nerve fibers.
This weakness can be caused by a myopathy to that muscle group. The bilateral triceps surae muscle, made up of the gastrocnemius and the soleus, is essential to maintain a straight posture while standing. This indicates that weakness to this muscle is the cause of the swaying and impaired posture in patients with astasis.
Changes in muscle performance can be broadly described as the upper motor neuron syndrome. These changes vary depending on the site and the extent of the lesion, and may include: Muscle weakness. [2] known as 'pyramidal weakness' Decreased control of active movement, particularly slowness; Spasticity, a velocity-dependent change in muscle tone
