Sensory Impairment

Share:

The somatosensory function is the ability to interpret bodily sensation (Puce, 2003). The sensory systems in our body control and transmit the signals from the periphery to the cerebral cortex. The somatosensory system controls your sense of touch, proprioception, temperature, pain, and itch. (Gardner and Martin,2000).

When sensation becomes impaired from neurodegeneration induced neuropathy and results in numbness or tingling (pins and needles) it is diagnosed as Paresthesia. Sensory impairment from Superficial Siderosis results from Sensory Peripheral Neuropathy. You may experience a reduced pain sensation (example: failure to feel dental pain) and reduced light touch sensation.

Your physician will be able to map which nerves are being affected by tracking the impairment. Problems in specific body areas will tell your doctor which nerve is impaired:

C=Cervical T=Thorasic L=Lumbar S=Sacral

1. The posterior aspect of the shoulders =(C4)
2. The Lateral aspect of the upper arms =(C5)
3. The medial aspect of the lower arms= (T1)
4. The tip of the thumb=(C6)
5. The tip of the middle finger =(C7)
6. The tip of the pinky finger=(C8)
7. The thorax at nipple level =(T5)
8. The thorax at umbilical level=(T10)
9. The upper part of the upper leg=(L2)
10.The lower-medial part of the upper leg=(L3)
11. The medial lower leg=(L4)
12. The lateral lower leg= (L5)
13. The sole =(S1)

Sources: Superficial siderosis is a rare neurologic disease characterized by progressive sensorineural hearing loss, cerebellar ataxia, pyramidal signs, and neuroimaging findings revealing hemosiderin deposits in the spinal and cranial leptomeninges and subpial layer. The disease progresses slowly, and patients may present with mild cognitive impairment, nystagmus, dysmetria, spasticity, dysdiadochokinesia, dysarthria, hyperreflexia, and Babinski signs. Additional features reported include dementia, urinary incontinence, anosmia, ageusia, and anisocoria. Superficial siderosis MedGen UID: 831707 •Concept ID: CN226971 •Finding Orphanet: ORPHA247245
