A term used to describe a lack of vigour or strength. This is a common symptom of a wide range of conditions, including anaemia, emotional problems, and various disorders affecting the heart, nervous system, bones, joints, and muscles. When associated with emotional disorders, weakness may represent a lack of desire or ambition, rather than loss of muscle strength. More specifically, the term describes loss of power in particular muscle groups, which may be accompanied by muscle wasting and loss of sensation. (See also paralysis.)
