Transient Ischaemic Attacks Or Episodes (tia, Tie): From 1 Different Sources

Episodes of transient ISCHAEMIA of some part of the cerebral hemispheres or the brain stem (see BRAIN) lasting anything from a few minutes to several hours and followed by complete recovery. By de?nition, the ischaemic episode must be less than 24 hours. These episodes may be isolated or they may occur several times in a day. The cause is ATHEROMA of the carotid or vertebral arteries (see ARTERIES, DISEASES OF) and the embolisation (see EMBOLISM) of PLATELETS or CHOLESTEROL. These attacks present with strokes (see STROKE) that rapidly recover.

Breath-holding Attacks

Periods during which a toddler holds his or her breath, usually as an expression of pain, frustration, or anger.

The child usually becomes red or even blue in the face after a few seconds, and may faint.

Breathing quickly resumes as a natural reflex, ending the attack.

Attacks cause no damage and are usually outgrown.... breath-holding attacks

Tietze’s Syndrome

Chest pain localized to an area on the front of the chest wall, usually made worse by movement of the arms or trunk or by pressure on the chest wall. The syndrome is caused by inflammation of 1 or several rib cartilages and symptoms may persist for months. Treatment is with analgesics, nonsteroidal anti-inflammatory drugs, or local injections of corticosteroid drugs into the cartilage.... tietze’s syndrome

Transient Ischaemic Attack

(TIA) A brief interruption of the blood supply to part of the brain, which causes temporary impairment of vision, speech, sensation, or movement. The episode typically lasts for several minutes or, at the most, for a few hours. TIAs are sometimes described as mini strokes, and they can be the prelude to a stroke.

TIAs may be caused by a blood clot (see embolism) temporarily blocking an artery that supplies the brain, or by narrowing of an artery as a result of atherosclerosis.

After a TIA, tests such as CT scanning, blood tests, ultrasound scanning, or angiography may be needed to determine a cause. In some cases, the heart is studied as a possible source of blood clots. Treatment is aimed at preventing stroke, which occurs within 5 years in up to one third of patients with TIA. Treatments include endarterectomy, anticoagulant drugs, or aspirin.... transient ischaemic attack

Ischaemic Stroke

A STROKE that occurs when the ?ow of blood to a part of the brain is interrupted by a partial or complete THROMBOSIS of the supplying artery or ARTERIES, or by a clot of blood that has detached itself from elsewhere in the circulatory system – for instance, a deep vein thrombosis (DVT) – and blocked a cerebral artery. Stroke is the second most common cause of death worldwide. Its treatment is di?cult and prevention is best targeted at those who are at the highest absolute risk of stroke, because such people are likely to derive the greatest bene?t. They generally have a history of occlusive vascular diseases such as previous ischaemic stroke or a transient ischaemic attack (TIA), coronary heart disease (see HEART, DISEASES OF) or PERIPHERAL VASCULAR DISEASE. In the UK strokes affect about 200 people per 100,000 population annually, with the incidence rising sharply after the age of 55. At the age of 70 the incidence is around 15 people per 1,000 of population; at 80 the ?gure is double that.

About 80 per cent of patients survive an acute stroke and they are at risk of a further episode within a few weeks and months; about 10 per cent in the ?rst year and 5 per cent a year after that. HYPERTENSION, smoking, HYPERLIPIDAEMIA and raised concentration of blood sugar, along with OBESITY, are signi?cant pointers to further strokes and preventive steps to reduce these factors are worthwhile, although the reduction in risk is hard to assess. Even so, the affected person should stop smoking, greatly reduce alcohol intake, check for and have treated diabetes, reduce weight and exercise regularly. In any case, a diet rich in fresh fruit and vegetables and low in fat and salt, exercise and the avoidance of smoking may reduce the risk of having a ?rst stroke.

The evidence is inconclusive that patients with ischaemic stroke should be treated with antihypertensives. Furthermore, neither the starting blood pressure nor the best drug regimen or its starting time are generally agreed. Studies on the most e?ective methods of preventing and treating stroke are continuing; meanwhile available evidence suggests that an active approach to prevention of primary and secondary hypertension will bene?t patients and usually be cost-e?ective.... ischaemic stroke

Panic Attacks

Panic attacks, or panic disorders, are recurrent short episodes of acute distress. Some sufferers may be mentally confused and fear impending death. Initially these attacks tend to occur unexpectedly but, if recurrent, they often become associated with certain places such as a con?ned space (lift) or among crowds. Symptoms include a feeling of breathing diffculties, including overbreathing, PALPITATION, dizziness, sweating, faintness and pains in the chest. Attacks are usually short (a few minutes) but not often associated with physical illness, although victims may have an anxiety disorder or PHOBIA. If troublesome or disabling, attacks can be treated symptomatically with short-term ANXIOLYTICS or on a long-term basis with BEHAVIOUR THERAPY.... panic attacks

Hypoxic-ischaemic Encephalopathy

(HIE, birth asphyxia, perinatal asphyxia) brain damage in a newborn infant as a result of the brain receiving inadequate oxygen. HIE may cause seizures and, if severe, death within minutes of oxygen deprivation. If the infant survives there can be significant long-term consequences, such as developmental delay, learning disabilities, or cerebral palsy.... hypoxic-ischaemic encephalopathy
