idiopathic
(adjective)
Of, relating to, or designating a disease or condition having no known cause.
Examples of idiopathic in the following topics:
-
Abnormal Curves of the Vertebral Column
- Scoliosis is typically classified as either congenital (caused by vertebral anomalies present at birth), idiopathic (cause unknown, subclassified as infantile, juvenile, adolescent, or adult, according to when onset occurred), or neuromuscular (having developed as a secondary symptom of another condition, such as spina bifida, cerebral palsy, spinal muscular atrophy, or physical trauma).
- It has been estimated that approximately 65% of scoliosis cases are idiopathic, 15% are congenital, and 10% are secondary to a neuromuscular disease.
- Idiopathic scoliosis is a condition which lasts a lifetime, but it does not lower one's expected life span.
- Adolescent idiopathic scoliosis has no clear causal agent.
- A 50-year follow-up study published in the Journal of the American Medical Association (2003) asserts that the lifelong physical health (including cardiopulmonary and neurological functions) and mental health of idiopathic scoliosis patients are comparable to those of the general population.
-
Bursitis
- Causes of bursitis include rheumatoid arthritis, severe scoliosis, traumatic injury, other chronic systemic diseases, and idiopathic sources.
-
Hypotonia and Hypertonia
- Some disorders have a specific treatment, but the principal treatment for most hypotonia of idiopathic or neurologic origin is physical and/or occupational therapy for remidiation.
-
Bell's Palsy
- Bell's palsy is defined as an idiopathic unilateral facial nerve paralysis, usually self-limiting.
- Bell's palsy is commonly referred to as idiopathic or cryptogenic, meaning that it is due to unknown causes.
-
Raynaud's Phenomenon
- It comprises both Raynaud's disease and Raynaud's syndrome; the former (also known as primary Raynaud's phenomenon) being when the phenomenon is idiopathic, and the latter (also known as secondary Raynaud's), which is caused by some other instigating factor, most commonly a connective tissue disorder such as systemic lupus erythematosus.
- Raynaud's disease, or primary Raynaud's, is diagnosed if the symptoms are idiopathic, that is, if they occur by themselves and not in association with other diseases.
-
Adrenal Gland Disorders
- One subtype is called idiopathic or unknown cause of adrenal insufficiency. 80% are due to an autoimmune disease called Addison's disease or autoimmune adrenalitis.
-
Cryptorchidism
- In most full-term infant boys with cryptorchidism but no other genital abnormalities, a cause cannot be found, making this a common, sporadic, unexplained (idiopathic) birth defect.
-
Facial (VII) Nerve
- Lower motor neuron lesions can result in a cranial nerve VII palsy (Bell's palsy is the idiopathic form of facial nerve palsy), manifested as both upper and lower facial weakness on the same side of the lesion.
-
Carpal Tunnel Syndrome
- Most cases of CTS are of unknown causes, or idiopathic.
-
Spinal Tap
- Increased levels of lactate can occur the presence of cancer of the central nervous system, multiple sclerosis, low blood pressure, low serum phosphorus, respiratory alkalosis, idiopathic seizures, traumatic brain injury, cerebral ischemia, brain abscess, hydrocephalus, or bacterial meningitis.
