Are sensory integration issues a real problem?
Heather Wittenberg, PhD, Psychology, answeredThere is some controversy over whether sensory integration issues are “legitimate”, from a medical standpoint. Many pediatricians will dismiss the topic as unfounded or irrelevant. Studies are ongoing as to the efficacy of treatment approaches. But while these studies continue, many parents are finding these approaches extremely helpful. In my practice, I have seen exceptional progress made in cases with sensory issues, and I work closely with occupational therapists (OTs) who provide invaluable assistance to families. I do often recommend that an OT conduct an evaluation of a child with behavioral difficulties.
What determines how fast nerve impulses travel?

What is agnosia?
Honor Society of Nursing (STTI) answered
Agnosia is a rare disorder characterized by the inability to recognize and identify objects or people. People suffering from agnosia may have difficulty recognizing the geometric features of an object or face, or may be able to perceive geometric features, but not know what the object is used for, or whether a face is familiar or not. Agnosia can be limited to one sensory modality, such as vision or hearing. For example, a person may have difficulty recognizing an object as a cup, or identifying a sound as a cough. Agnosia can result from strokes, dementia, developmental disorders, or other neurological conditions. It typically results from damage to specific areas in the occipital or parietal lobes of the brain. People with agnosia may retain their cognitive abilities in other areas.
