Diagnosis of carotid sinus hypersensitivity in older adults: carotid sinus massage in the upright position is essential. The nature and sequence of cellular events in sensitized hosts suggests the involvement of multiple hypersensitivity reactions in the expression of resistance. A specific feature noted in elderly patients is that the deficiency suppresses delayed cutaneous hypersensitivity. However, the authors concluded that this may have been due to high levels of pregnancy-induced androgens or endorgan hypersensitivity to normal pregnancy levels of androgen. Prevalence of cardioinhibitory carotid sinus hypersensitivity in patients 50 years or over presenting to the accident and emergency department with 'unexplained' or 'recurrent' falls. Often triggered by hypersensitivity to specific stimuli, the individual experiences escalating agitation followed by an abrupt outburst of aggressive and threatening behavior. In this study, we have shown that this visceral hypersensitivity is also associated with microglial activation. These correlations between behavioral and biochemical observations indicate that protein phosphorylation plays a key role in the initiation of central sensitization and, subsequently, pain hypersensitivity. Orthostatic hypotension, carotid sinus hypersensitivity and vasosagal syncope occur as isolated diagnoses in younger patients but occur in combination in older patients. Rare patients present penicillin hypersensitivity, and there are some recorded instances of severe reaction, even including death. A deficit in the transient system therefore has some of the same consequences as a hypersensitivity in the sustained system. Abnormalities in visual function have been documented in subjects suffering from primary headaches, with a demonstrated hypersensitivity to light in migraine patients. Other mechanisms that could potentially cause cognitive decline are autoimmune vasculitis or allergic hypersensitivity responses to the chemotherapeutic medications. At present, these will perhaps be considered in cases with hypersensitivity and intolerability to conventional drugs.
