What are common neurological sensory deficits?
Peripheral neuropathy
What are age-related sensory alterations of vision?
Presbyopia, reduced visual fields, increased glare sensitivity, decreased night vision, reduced depth perception
What happens when cataracts form?
Cloudy lenses
Blurry vision
Dull colors
What happens during glaucoma?
Damage to optic nerve
Loss of peripheral vision
Eye drops for treatment
Cannot reverse damage that has occurred
What happens is macular degeneration?
Loss of central vision - high concentration of rods and cones
Accumulation of deposits on macula cells
What is expressive aphasia?
Inability to name common objects or express simple ideas in words or writing (more common with L CVA)
