Weakness
Weakness
Weakness (/ˈwiːknɪs/), also known as Asthenia, is a symptom of a number of different conditions. 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 congenital myopathy. It occurs in Neuromuscular disease due to muscular weakness. Perceived weakness (or non-neuromuscular) describes a condition where a person feels more effort than normal is required to exert a given amount of force but actual muscle strength is normal.
Etymology
The term "weakness" comes from the Old Norse word "veikr", which means "lacking strength".
