Sensory deficits following a brain injury are usually the result of damage to either the right side of the brain or the parietal and occipital lobe region. Sensory deficits are those to do with hearing, smell, taste, touch and body language such as emotional and non-verbal signals. These deficits can lead to lack of communication, confusion and frustration. Some may even develop tinnitus, a ringing in the ears.
Other deficits may be auditory perception having to do with sounds and problems to do with visual perception relating to colour confusions, shapes, size, depth and distance. Those who suffer from the sensory deficit of vision loss may experience problems with hand-eye coordination or having blind spots or double vision and may, as a result, be somewhat clumsy.
Another sensory deficit is textile perception relating to pain, pressure and temperature. The skin may also tingle or itch excessively. Olfactory perceptions relates to smells where everything has an unpleasant odor, and gustatory perceptions relate to taste where everything tastes bitter are other deficits.
