  2. Autonomic dysreflexia - Wikipedia

    en.wikipedia.org/wiki/Autonomic_dysreflexia

    Autonomic dysreflexia (AD) is a life-threatening medical emergency characterized by hypertension and cardiac arrhythmias. [1] This condition is sometimes referred to as autonomic hyperreflexia. [ 2 ] Most cases of AD occur in individuals with spinal cord injuries. [ 3 ]

  3. Spinal shock - Wikipedia

    en.wikipedia.org/wiki/Spinal_shock

    The term "spinal shock" was introduced more than 150 years ago in an attempt to distinguish arterial hypotension due to a hemorrhagic source from arterial hypotension due to loss of sympathetic tone resulting from spinal cord injury. Whytt, however, may have discussed the same phenomenon a century earlier, although no descriptive term was assigned.

  4. Hyporeflexia - Wikipedia

    en.wikipedia.org/wiki/Hyporeflexia

    In spinal shock, which is commonly seen in the transection of the spinal cord, hyporeflexia can transiently occur below the level of the lesion and can later become hyperreflexic. Cases of severe muscle atrophy or destruction may render the muscle too weak to show any reflex and should not be confused with a neuronal cause.

  5. Hyperreflexia - Wikipedia

    en.wikipedia.org/wiki/Hyperreflexia

    Spinal cord injury is the most common cause of hyperreflexia. [citation needed] Standard stimuli, such as the filling of the bladder, can cause excessive responses from the nervous system. The causes of hyperreflexia are not known. [citation needed]

  6. Dysautonomia - Wikipedia

    en.wikipedia.org/wiki/Dysautonomia

    Paraneoplastic syndrome [25] Spinal cord injury [13] or traumatic brain injury [26] Synucleinopathy, a group of neurodegenerative diseases including pure autonomic failure, Parkinson's disease, dementia with Lewy bodies and multiple system atrophy [6] Surgery or injury involving the nerves [13] Toxicity (vincristine) [27]

  7. Spinal cord injury - Wikipedia

    en.wikipedia.org/wiki/Spinal_cord_injury

    A spinal cord injury (SCI) is damage to the spinal cord that causes temporary or permanent changes in its function. It is a destructive neurological and pathological state that causes major motor, sensory and autonomic dysfunctions. [3]

  8. Paroxysmal sympathetic hyperactivity - Wikipedia

    en.wikipedia.org/wiki/Paroxysmal_sympathetic...

    Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system. Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis , and hyperthermia . [ 1 ]

  9. Primary autonomic failure - Wikipedia

    en.wikipedia.org/wiki/Primary_autonomic_failure

    In primary dysautonomias, the autonomic dysfunction occurs as a primary condition (as opposed to resulting from another disease). [1] Autonomic failure is categorized as "primary" when believed to result from a chronic condition characterized by degeneration of the autonomic nervous system, or where autonomic failure is the predominant symptom ...
