Disturbed sensory and perceptual function

1. Disturbed sensory and perceptual function Presented by J. Karl Pineda

2. Etiology • Agnosia- total or partial loss of the ability to recognize objects or people through sensory stimuli as a results of organic brain damage

3. Types of Agnosia • Form agnosia- patient perceive only parts of detail, not the whole object.

4. Finger agnosia- is the inability to distinguish the fingers on the hand. It is present in lesions of the dominant parietal lobe, and is a component of gerstamm syndrome Types of Agnosia

5. Types of agnosia • Simultanagnosia: Patients can recognize objects or details in their visual field, but only one at a time. They cannot make out the scene they belong to or make out a whole image out of the details. They literally cannot see the forest from the trees. Simultanagnosia is a common symptom of Balint's syndrome.

6. Subjective Data • Patient’s understanding of the sensory disturbance • Measures that relieve the symptoms • Presence of symptoms that occur with the sensory problems

7. Objective Data • Noting the patients ability to perform purposeful movements or to recognize familiar objects.

8. Interventions

9. Interventions • Teaching patient with sensory dysfunction protective measures in relation to the sensory deficit or alterations

10. Interventions • Teach patient to inspect parts of the body that have no feeling • Protect sensitive body parts from the discomfort of linen rubbing over them

11. Interventions • If a patient has a deficit in one sense, he should be taught to compensate with another
