LESION IN SENSORY SYSTEM

LESIONS	CAUSES	MANIFESTATIONS
Peripheral nerve A)Mononeuropathy	Lesion of one peripheral nerve	Loss of all sensation supplied by it
B)polyneuropathy	Lesion of all peripheral nerves     - diabetic  - peripheral neuritis	Loss of all sensation -GLOVE AND STOCKING LOSS
C)Herpes Zoster	Herpes virus infect DRG	irritation of pain afferent migrate toward peripheral axon =rash +vesicular formation
Spinal cord A)Tabes Dorsalis	Neurosyphilitic Attack dorsal root center to DRG	Atrophy of Dorsal column =loss fine touch,vibration,proprioceptive ~SENSORY ATAXIA
B)Syringomyelia	Widening of central canal Damage spinothalamic tract	Loss pain,temp,crude touch =JACKET LOSS (normally cervical region is affected)
C)Brown Sequard Syndrome	Hemisection of spinal cord	At level of lesion =sensory:loss all sensation =motor   :loss all reflexes(LMNL) Below level of lesion =same side:loss the dorsal column sensation + UMNL in motor reflex =oppose side:loss the spinothalamic tract sensation only
Thalamic Thalamic Syndrome		Complete sensory loss in opposite side
Cortical Sensory cortex lesion		Loss of: Fine touch Stereognosis Proprioceptive sensation Pressure
Amorphosynthesis	Damage to the somatic sensation on one side	Loss ability to recognize complex object Disturbance of body image
