Multi-infarct dementia results from a series of small strokes affecting several brain regions. Stroke-related dementia involving successive small strokes causes a more gradual decline in cognition. [4] Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older).
Massive, rapid elevations in blood pressure can trigger any of these symptoms, and warrant further work-up by physicians. Physical exam would include measurement of blood pressure in both arms. Laboratory tests to be conducted include urine toxicology, blood glucose, a basic metabolic panel evaluating kidney function, or a complete metabolic ...
The rapid heart rate, if fast enough, reduces the opportunity for the "pump" to fill between beats decreasing cardiac output and consequently blood pressure. The following symptoms are typical with a rate of 150–270 or more beats per minute: [11] Pounding heart; Rapid heart beat; Shortness of breath; Chest pain; Rapid breathing; Dizziness ...
The first symptoms are often mistakenly attributed to aging or stress. [34] Detailed neuropsychological testing can reveal mild cognitive difficulties up to eight years before a person fulfills the clinical criteria for diagnosis of Alzheimer's disease. [35] These early symptoms can affect the most complex activities of daily living. [36]
Childhood dementia is very often diagnosed late, misdiagnosed, or not diagnosed at all. [9] A correct diagnosis happens, on average, 2 years or more after symptoms become apparent. Additionally, children affected by childhood dementia are often misdiagnosed with: Autism [16] [9] [17] Developmental or intellectual delay [16] [9] ADHD [9] Others [9]
In adults and children over 15, resting heart rate faster than 100 beats per minute is labeled tachycardia. Tachycardia may result in palpitation; however, tachycardia is not necessarily an arrhythmia. Increased heart rate is a normal response to physical exercise or emotional stress.
The ventricular tachycardia may take a characteristic form known as bidirectional ventricular tachycardia. This form of ventricular tachycardia occurs relatively infrequently, but if seen is suggestive of an underlying diagnosis of CPVT or the related condition Andersen-Tawil syndrome .
[68] β-blockers improve left ventricular filling and relaxation and thereby lessen symptoms. In some children, β–blockers (e.g., propranolol) were shown effective to reduce the risk of sudden death. [68] Further, calcium channel blockers (verapamil) and antiarrhythmic drugs may be used as an adjunct therapy to β-blockers in symptomatic ...
