Another factor in secondary injury is loss of cerebral autoregulation, the ability of the brain's blood vessels to regulate cerebral blood flow. [5] Other factors in secondary damage are breakdown of the blood–brain barrier, edema, ischemia and hypoxia. [15] Ischemia is one of the leading causes of secondary brain damage after head trauma. [9]
The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. Other effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage.
This discharge type is the most common type of ESD in electronic devices and causes most of the ESD damages in their manufacturing. CDM discharge depends mainly on parasitic parameters of the discharge and strongly depends on size and type of component package. One of the most widely used CDM simulation test models is defined by the JEDEC.
Radiation and chemotherapy can lead to brain tissue damage by disrupting or stopping blood flow to the affected areas of the brain. This damage can cause long term effects such as but not limited to; memory loss, confusion, and loss of cognitive function. The brain damage caused by radiation depends on where the brain tumor is located, the ...
Symbol for an ESD protection device – EPA Alternate warning symbol Symbol of an ESD grounding point for all components. An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors.

Brain healing is the process that occurs after the brain has been damaged. If an individual survives brain damage, the brain has a remarkable ability to adapt. When cells in the brain are damaged and die, for instance by stroke, there will be no repair or scar formation for those cells.
As a result, this memory favoring pathway is stopped, and the brain loses essential memory function. The loss of memory is a symptom of neurodegenerative disease, including AD. Another way Aβ causes cell death is through the phosphorylation of AKT; this occurs as the phosphate group is bound to several sites on the protein. This ...
Following research, excitotoxicity appears to be the likely mode of action for BMAA which acts as a glutamate agonist, activating AMPA and NMDA receptors and causing damage to cells even at relatively low concentrations of 10 μM. [31] The subsequent uncontrolled influx of Ca 2+ then leads to the pathophysiology described above.
