Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.
Conversion disorder presented motor or sensory symptoms including: Motor symptoms or deficits: Impaired coordination or balance; Weakness/paralysis of a limb or the entire body (hysterical paralysis or motor conversion disorders) Impairment or loss of speech (hysterical aphonia) Difficulty swallowing or a sensation of a lump in the throat
Dual sensory loss is the simultaneous loss of two senses. Research has shown that 6% of non-institutionalized older adults had a dual sensory impairment, and 70% of severely visually impaired older adults additionally suffered from significant hearing loss. [7] Vision and hearing loss both interfere with the interpretation and comprehension of ...
This category encompasses all disorders of the nervous system. The major meta-categories is Category:Neurological disorders by disease category.A disorder can be categorized in both systems simultaneously (for example, glioma under "Nervous system neoplasia" AND "Brain disorders").
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]
The damage may result in loss of feeling, paralysis, weakness, [4] and stiffness in the back, shoulders, and extremities. Syringomyelia may also cause a loss of the ability to feel extremes of hot or cold, especially in the hands. It may also lead to a cape-like bilateral loss of pain and temperature sensation along the upper chest and arms.
Chronic RBD is idiopathic, meaning of unknown origin, or associated with neurological disorders. [22] There is a growing association of chronic RBD with neurodegenerative disorders— Parkinson's disease , multiple system atrophy (MSA), or dementia—as an early indicator of these conditions by as much as 10 years.
Paralysis (pl.: paralyses; also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. [1]
