Weakness is a symptom of many different medical conditions. [1] The causes are many and can be divided into conditions that have 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 .
Generalized MG has muscle weakness with a variable combination of the bulbar, axial, or limb and respiratory muscles. [ 54 ] Patients can also be sub-grouped by the age of onset: juvenile-onset MG (onset age ≤ 18 years of age), early-onset MG (EOMG; 19–50 years of age), late-onset MG (LOMG; onset > 50 years of age), and very late-onset ...
Amongst patients admitted to intensive care units (ICUs), hypoalbuminemia is specifically associated with ICU-acquired muscle weakness. [14] In chronic kidney disease , hypoalbuminemia is an indicator of frailty , which is itself associated with complications, mental distress , quality of life impairment, resource utilization, and mortality.
Ocular myasthenia gravis (MG) is a disease of the neuromuscular junction resulting in hallmark variability in muscle weakness and fatigability. MG is an autoimmune disease where anomalous antibodies are produced against the naturally occurring acetylcholine receptors in voluntary muscles.
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 be caused by low levels of potassium and other electrolytes within muscle cells. It can be temporary or ...
Generalized weakness or tiredness may also occur. Some also report difficulty concentrating, blurred vision, tremulousness, vertigo, anxiety, palpitations (awareness of the heartbeat), unsteadiness, feeling sweaty or clammy, and sometimes nausea. A person may look pale. [12]
Deficiency of magnesium can cause tiredness, generalized weakness, muscle cramps, abnormal heart rhythms, increased irritability of the nervous system with tremors, paresthesias, palpitations, low potassium levels in the blood, hypoparathyroidism which might result in low calcium levels in the blood, chondrocalcinosis, spasticity and tetany, migraines, epileptic seizures, [7] basal ganglia ...
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.
