How do the elements in Groups 5A, 6A, & 7A form ions? They gain electrons to achieve noble gas configuration and form anions with a negative charge. What is the formula unit of Aluminum oxide?
Distal anhidrosis, although often subclinical, is detectable by clinical sudomotor testing in many patients with peripheral neuropathy. Diabetes mellitus, the most common cause of autonomic neuropathy in the developed world, typically impairs thermoregulatory sweating in a stocking and glove distribution. As the neuropathy progresses, asymmetric truncal anhidrosis or global anhidrosis may develop.
Hyperhidrosis can be caused by dysfunction of the autonomic nervous system (ANS). Sweating is controlled through the opposing actions of the sympathetic and parasympathetic divisions of the ANS. If the sympathetic system (âfight or flightâ system) is overly stimulated, for instance, excessive sweating will occur.
