Whatever the cause, thiamine deficiency generally leads to absent DTRs and loss of position sensation. Unless patients walk in the dark – a task relying on position sense generated in the legs and feet – their deficits may actually remain asymptomatic. In the well-known Wernicke–Korsakoff s...

loss of neural function causes trophic changes in muscle, bone, skin, hair, nails, etc; structural changes caused by lack of nervous stimulation, not using the affected area, immobility, lack of weight bearing, muscle weakness and atrophy; recurrent injury to the area may cause infection or st...
Loss of coordination and balance. Changes in skin, hair, or nails. Sexual dysfunction, particularly in men. While these symptoms can give you a hint, a proper diagnosis is vital to confirm neuropathy. The process usually begins with a thorough medical history and physical exam. Your healthcare...
In rare cases, patients experience loss of power in the legs, in which sensory loss is greater than motor loss; the etiology is axonal loss. One week after the removal of vitamin B6 from the diet, levels of xanthurenic acid increase and levels of pyridoxine decrease in the urine. At 3...
reports that approximately 2.1 million people worldwide suffer from multiple sclerosis2. When the peripheral nerves in the extremities become damaged, the patient experiences numbness and tingling in the arms and legs, weakness or paralysis of muscles in the arms or legs, tremors and a loss of ...
(1852). By the 1970s, there were reports of sensory deficits in the legs with painless ulcers and fractures in other kinships (Ohta et al., 1973) prompting investigations into the underlying etiologies of the genetic inheritance pattern, age at onset and dominant clinical featur...
Two weeks later, he developed painful ascending paraesthesias involving legs up to knees and hands up to wrists. This was associated with difficulty in walking independently. The patient also used to smoke illicit imported cigarettes. He was provisionally diagnosed to have chronic inflammatory ...
3 Briefly, rats were allowed to crawl into a perspex cylindrical restrainer with slanted vents on the side for the hind legs to freely extend and acclimatized for 10 to 15 minutes, after which the hind paws were exposed to the test stimulus. Paw-withdrawal thresholds were determined before ...
