Postorgasmic illness syndrome (POIS) is a syndrome involving chronic physical and cognitive symptoms following orgasm. [1] The symptoms usually onset within seconds, minutes, or hours, and last for up to a week. [1] The cause and prevalence are unknown; [2] it is considered a rare disease. [3] It typically affects men but in rare instances can ...
Slight weakness in a limb may be tolerated, but slight weakness in the extraocular muscles would lead to misalignment of the two eyes, even a small degree of which could lead to diplopia. Eyes may also be less able to adapt to variable weakness, because extraocular muscles use visual rather than proprioceptive (body position-sensing) cues for ...
The muscle weakness that worsens with activity (abnormal muscle fatigue) in myasthenia gravis [66] is a symptom shared by other neuromuscular diseases. Most of the metabolic myopathies, such as McArdle disease (GSD-V), have abnormal muscle fatigue rather than fixed muscle weakness.
Myelitis causes spinal cord dysfunction, which can result in muscle weakness, paralysis in the limbs, lost or reduced sensation, spasms, loss of bladder and bowel control, or erectile dysfunction. [1] [4] [2] [7] [8] [9] The myelitis can be transverse, affecting an entire cross-section of the spinal cord, and showing bilateral symptoms.
This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the brain). This muscular defect typically results in myalgia (muscle pain), muscle weakness (reduced muscle force), or premature muscle fatigue (initially normal, but declining muscle force).
The main symptom of benign fasciculation syndrome is focal or widespread involuntary muscle activity (fasciculation). [1] The benign twitches usually have a constant location. [2] Other common symptoms are generalized fatigue or weakness, paraesthesia or numbness, and muscle cramping or spasms. [1]
Weakness of the eye muscles is uncommon. Some may have double vision, drooping of the eyelids and difficulty swallowing, [4] but generally only together with leg weakness; this too distinguishes LEMS from myasthenia gravis, in which eye signs are much more common. [3] In the advanced stages of the disease, weakness of the respiratory muscles ...
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 ...
