Description: A subtype of orthostatic hypotension where the autonomic dysfunction that impairs or blunts the reflex tachycardia and/or vasoconstriction is caused by a neurological disorder. Possible underlying conditions include dysfunction of the: Central autonomic system: e.g., due to Parkinson ...
syncope due to orthostatic hypotension/intolerance 4 syncope due to autonomic dysfunction, dysautonomia, or postural orthostatic tachycardia syndrome (POTS), which may include neutrally mediated syncope 4 cardiac syncope, including arrhythmia and structural disease causes ...
Keywords Children Syncope POTS Orthostatic intolerance Autonomic dysfunction 1. Introduction The interest in orthostatic intolerance with its different facets and the autonomic nervous system has increased in recent years. One important reason could be increased knowledge in the field and publication of guid...
Thus, a TLOC episode should not be considered syncope if a medical intervention is required to reverse the loss of consciousness. Similarly, if cerebral dysfunction is not due to insufficient cerebral nutrient flow, the loss of consciousness or apparent loss of consciousness should not be termed ...
Therefore, Pmax and Pd may be altered due to autonomic dysfunction. Autonomic dysfunction, particularly increased sympathetic nerve excitability, notably prolongs both Pmax and Pd [23]. Köse et al. [24] found that Pmax and Pd of HUTT-positive patients were significantly greater than those in...
What is terminal autonomic failure? What is the pathophysiology of seizures? What are the causes of feeling faint when standing? What is a grand mal seizure? What is a brain aneurysm? What is a carotid transient ischemic attack? What is autonomic dysfunction?
To propose a new test to evaluate the autonomic nervous system in patients with syncope: Multimodal Monitoring for Diagnosis of Dysautonomia (MMDD). We included 21 patients with syncope (16 female, 6 male, mean age 43.5 years) and 21 with no-syncope subjects (15 female, 7 male, mean age...
The second case is a 79-year-old female with Parkinson's disease for many years and a primary autonomic dysfunction leading to dizziness and syncope due to pronounced blood pressure fluctuations with hypertensive and hypotensive phases. The last patient is a 22-year-old female with postural ...
It is difficult to explain a temporary loss of consciousness as a result of hypoglycemia. Demonstration that hypoglycemia can be transient, with the patient suffering from neuroglycopenia without autonomic symptoms due to delayed counterregulation, might be a first step in confirming that a diabetic ...
