constriction or narrowing of a passage or opening, for example of the valves of the heart

irregular contractions of the myocardium secondary to electrical disturbances in the heart
wide spread hardening of the arteries
clouding of the lens of the eye. can be slight, causing some visual disturbance, or significant, severely obstructing light from entering the eye. if sufficient light cannot pass into the eye for focusing the retina, then it becomes difficult of impossible to see clearly
second leading cause of blindness in US, a disease process in which increased intraocular pressure damages the optic nerve and inhibits the ability of the eye to transmit visual info properly
typically occurs in older adults and affects the ability to see objects in the center of the visual field. there may be enough peripheral vision left intact that the person can still carry on with most activities of daily life
condition where the retina (the light-sensitive portion of the posterior eye) becomes detached from the supportive tissue behind it. the retina converts light images to nerve impulses for transmission via the optic nerve to the bran.
progressive, bilateral, and symmetrical hearing loss from the effects of aging
any derangement or abnormal function of the motor, sensory, and autonomic nerve tracts. could be diffuse, involving multiple neurons and nerve tracts that affect many parts of the body, or focal neurons that affect a single, specific nerve and part of the body. generally includes pain, numbness, tingling, swelling, muscle weakness, or even absent pain perception.

the four most common causes of SOB:
adverse or toxic reaction to a drug or drugs, a condition for which the elderly patient is more at risk than the younger patient
condition resulting from the malfunctioning of normal brain activity. a chronic, irreversible condition that can be severely worsened by infection, med change, trauma, or other acute condition.
a serious disturbance in mental abilities that results in confused thinking and reduced awareness of your environment.
