What Causes Sensory Loss?
Sensory loss can be caused by problems in the central or peripheral nervous system. The central nervous system includes the brain and spinal cord, while the peripheral nervous system consists of nerves outside the brain and spinal cord. Identifying the location of the issue is crucial to narrowing down the diagnosis and finding the right treatment.
Different Types of Sensory Loss
Sensory loss can manifest in various ways. Hypoesthesia refers to a reduced ability to feel sensations like pain or temperature, while anesthesia means a complete inability to feel them. Other types include hypalgesia, a decreased sensitivity to pain, and analgesia, which is a total lack of pain sensation.
How to Diagnose Sensory Loss
Diagnosing sensory loss involves a thorough examination of the sensory system. Doctors use tests to assess touch, vibration, temperature, and pain sensations. They may also perform more specialized tests if a cortical lesion is suspected, such as examining two-point discrimination or graphesthesia.
