Last reviewed 01/2018
Paraesthesiae result from disordered function in the pathways connecting the finer and discriminative aspects of sensibility. This may be caused by:
- ischaemia of peripheral nerves
- pH changes affecting calcium ions and nerve conduction, as in hyperventilation and metabolic disturbances
- polyneuropathy
- transient ischaemia of the sensory cortex
- sensory jacksonian epilepsy due to a cortical lesion
- posterior column lesions of the spinal cord
