Sensory processing disorder (SPD), formerly known as sensory integration dysfunction, is a condition in which multisensory input is not adequately processed in order to provide appropriate responses to the demands of the environment.
Dual sensory loss is the simultaneous loss of two senses. Research has shown that 6% of non-institutionalized older adults had a dual sensory impairment, and 70% of severely visually impaired older adults additionally suffered from significant hearing loss. [7] Vision and hearing loss both interfere with the interpretation and comprehension of ...
The second type of sensor is a high spatial resolution sensor which can be compared to a human fingertip and is essential for the tactile acuity in robotic hands. The third and final tactile sensor type is a low spatial resolution sensor which has similar tactile acuity as the skin on one's back or arm. [6]
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome, is a neurodevelopmental disorder affecting the way the brain processes sounds. [2] Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the ...
Sensory hearing loss often occurs as a consequence of damaged or deficient cochlear hair cells. [disputed – discuss] Hair cells may be abnormal at birth or damaged during the lifetime of an individual. There are both external causes of damage, including infection, and ototoxic drugs, as well as intrinsic causes, including genetic mutations.
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [ 1 ]
Some people have an abnormally high or low absolute threshold for one or more senses that interferes with their quality of life. They tend to avoid stimulation, seek after it, or perhaps not notice it at all. This can be diagnosed as a sensory processing disorder, also known as sensory integration dysfunction, which is common in people with autism.
A Cochrane Review in 2017 assessed the effects of different interventions for the management of taste disturbances. There was very low-quality evidence to support the role of zinc supplementation in the improvement of taste acuity and taste discrimination in patients with zinc deficiency or idiopathic taste disorders.
