Sensory deprivation in geriatric patients.
Sensory deprivation speeds up the degenerative changes normally associated with aging and enhances the loss of functional cells in the central nervous system. Since it connotes reduction or absence of stimulation of the five senses, it involves the patient's physical activity, social relationships, intellectual status and overall "value system." Geriatric patients with various illnesses are particularly vulnerable to sensory deprivation, which becomes increasingly pronounced as physical or mental deterioration progresses. All cells require stimulation for continued growth and activity; lack of stimulation leads to atrophy, with secondary physical or psychosocial abnormalities. Depression acts as a negative reinforcement of stimuli, and anxiety acts as a blocking mechanism. The goal of rehabilitation is to maintain and strengthen the patient's social values and to preserve mental and physical motility. The recommended procedure involves assessment of medical, psychologic and social factors, and determination of whether organic disease is present. A specific treatment plan to meet the individualized needs of each patient is then established so as to minimize sensory deprivation and maximize physical and mental functioning. Re-evaluation (physical and psychologic) at regular intervals establishes a pattern not only for individual comparison but for comparison with results in untreated control groups.
