This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e ...
Spinal shock, loss of neural activity including reflexes below the level of injury, occurs shortly after the injury and usually goes away within a day. [42] Priapism, an erection of the penis may be a sign of acute spinal cord injury. [43] The specific parts of the body affected by loss of function are determined by the level of injury.
Functional visual loss (FVL) also known as Functional vision loss or Nonorganic visual loss (NOVL) is a reduction in visual acuity or loss of visual field that has no physiological or organic basis. This disease can come under the spectrum of functional neurological disorder or somatic symptom disorder .
Functional disorders are mostly understood as conditions characterised by: persistent and troublesome symptoms; associated with impairment or disability; where the pathophysiological basis is related to problems with the functioning and communication of the body systems (as opposed to disease affecting the structure of organs or tissues)
There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle.

Positive features of functional weakness on examination include Hoover's sign, when there is weakness of hip extension which normalizes with contralateral hip flexion. [16] Signs of functional tremor include entrainment and distractibility. The patient with tremor should be asked to copy rhythmical movements with one hand or foot.
Central cord syndrome (CCS) is the most common form of cervical spinal cord injury (SCI). It is characterized by loss of power and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to major injury to the central corticospinal tract of the spinal cord. [1]
Cases involving these symptoms are classified as functional disorders ("functional" in this context is usually contrasted with the old term "organic disease"). For example, in functional neurologic disorder (FND), those affected present with various neurological symptoms such as functional seizures, numbness, paresthesia, and weakness, among ...
