Neurosensory COGNITION- SENSORYPERCEPTION

Neurosensory The Human Brain Has More Connections Than There are Stars In The Universe The nervous system is one of the glories of nature. It has been said that the first hundred brains you see, you are amazed by the similarity. From there on you are amazed by the individuality.

Neurosensory The ability of an individual to make sense of their situation, learn new information and recall past memories. Performance of these activities rely on intact cognition, sensation and perceptual abilities.

Cognition The intellectual ability to think- includes memory, judgment and orientation. Also includes � LOC � Arousal �Awareness. �Memory �Affect �Judgment �Language

Sensation �The ability to receive and process stimuli through the sensory organs. Internal : processed through kinesthetic and visceral modes External: Processed through sight, hearing, smell, touch, and taste. Sterognosis: Ability to identify an object based on touch.

Sensory Perception �The ability to experience, recognize, organize and interpret sensory stimuli into meaningful information. Five senses �Take place in the brain.

Review of Sensory System Vision: Impairments range from minor distortion to complete blindness. Psychosocial consequences include learning difficulties, depression, anxiety, loss of self-worth, and difficulties with interpersonal relationships. Hearing: Impairments range from minor distortions of speech to complete hearing loss. Psychosocial consequences include problems with relationships, learning, and work, isolation, and frustration.

Review of Sensory System �Taste/Smell: Impairments can result in anorexia, weight loss, and malnutrition Food poisoning can occur from the ingestion of spoiled food. Psychosocial consequences impact one’s quality of life. �Touch: Impairments range from minor distortion of touch to a complete loss of touch sensation. Injury (i. e. , decreased ability to sense pain, heat, or cold) may develop.

Common Diagnostic Tests �Vision Visual fields test, noncontact tonometry �Hearing Pure tone air conduction hearing test, otoacoustic emissions (OAEs), auditory brainstem response (ABR)

Nursing Process Nursing Diagnosis Ø Disturbed sensory perception Ø Disturbed thought processes Ø Social Isolation Ø Risk for injury Planning and Implementation The goal /outcome is to improve, maximize or maintain current function

Planning 14 �Goals and outcomes Partner with the patient Incorporate what you know about the patient’s sensory problems �Setting priorities Type and extent of sensory alteration Safety Patient preferences �Teamwork and collaboration Copyright © 2017, Elsevier Inc. All Rights Reserved.

Nursing Interventions �What are some safety measure you could implement to ensure the safety of patients with impaired cognition and or sensory deficits.

Collaborative Interventions �Vision Surgery � Visual acuity correction, cataract, � Pharmacotherapy � steroidal, analgesic Adaptive methods � Eyeglasses, contact lenses, braille, guide dogs

Collaborative Interventions (cont’d) �Hearing Surgery � Pharmacotherapy � cochlear implants Antimicrobial, steroidal, analgesic Adaptive methods � Hearing aids, assistive listening, sign language

� Your brain is your most valuable possession! Take care of it! Brain Tips: Eat lots of fresh fruits and vegetables, whole grains and fish (especially salmon and tuna). Consider supplementing your diet with B vitamins and antioxidants. Avoid fatty meats, fried foods and full fat dairy products. Avoid caffeine, alcohol and tobacco. Never inhale solvents like gasoline or airplane glue. Always wear appropriate protective headgear (helmets) for sports and other activities. � It's no secret that long-term diet and nutrition choices have an effect on the way we look and feel; but new studies show that nutrition can also affect the way we think. As it turns out, there really is such a thing as “food for thought. ”
