If a seizure happens during the infection itself, the person most likely does not have epilepsy but has "symptomatic seizures" or seizures occurring because of a known injury to the brain. Once the infection is stopped the seizures will stop. Another more common infection is "meningitis", infection of the membranes surrounding the brain. Since ...
Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.

In rats, it has been shown that neurons often die a full 24 hours after blood flow returns. Some theorize that this delayed reaction derives from the various inflammatory immune responses that occur during reperfusion. [11] These inflammatory responses cause intracranial pressure, pressure which leads to cell injury and in some situations cell ...
Each year, six million Americans experience at least one panic attack, according to the Anxiety and Depression Association of America.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
It may occur via direct contact between cells (i.e., via gap junctions), as in an electrical synapse, but most commonly occurs via the vesicular release of neurotransmitters from the presynaptic axon terminal into the synaptic cleft, as in a chemical synapse.
Or, in layperson terms, an intensely pleasurable response to sexual stimulation that involves both the brain (neurons) and the body (muscles). That said, Dr. Wise tells us that “orgasms exist on ...
Epilepsy may occur as a result of several other conditions, including tumors, strokes, head trauma, previous infections of the central nervous system, genetic abnormalities, and as a result of brain damage around the time of birth. [30] [31] Of those with brain tumors, almost 30% have epilepsy, making them the cause of about 4% of cases. [72]
