Acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder such as fetal alcohol syndrome, perinatal illness or perinatal hypoxia. [1] ABI can result in cognitive, physical, emotional, or behavioural impairments that lead to permanent or temporary changes in functioning. [1]
Cognitive symptoms include confusion, aggressiveness, abnormal behavior, slurred speech, and coma or other disorders of consciousness. Physical symptoms include headaches that worsen or do not go away, vomiting or nausea, convulsions , brain pulsation, abnormal dilation of the eyes , inability to awaken from sleep, weakness in extremities, and ...
Ankle-brachial index (ABI) testing to compare blood pressure in your ankle and arm to help detect peripheral artery disease. Electrocardiogram (ECG) to measure the electrical activity of your heart
Childhood (or paediatric) acquired brain injury (ABI) is the term given to any injury to the brain that occurs during childhood but after birth and the immediate neonatal period. It excludes injuries sustained as a result of genetic or congenital disorder.
The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
Symptoms include tingling sensation (usually in the limbs), abnormal heartbeat, painful muscle cramps, and seizures. Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia , and this can cause transient dizziness, fainting, and anxiety . [ 3 ]
If an ABI >1.40 is calculated, this could indicate vessel wall stiffness caused by calcification, which can occur in people with uncontrolled diabetes. Abnormally high ABIs (>1.40) are usually considered false negatives, and thus, such results merit further investigation and higher-level studies. [56]
Hypernatremia, also spelled hypernatraemia, is a high concentration of sodium in the blood. [3] Early symptoms may include a strong feeling of thirst, weakness, nausea, and loss of appetite. [1] Severe symptoms include confusion, muscle twitching, and bleeding in or around the brain.
