What causes transient neurological symptoms?

What causes transient neurological symptoms?

The most common causes of transient neurological dysfunction include transient ischemic attack (TIA), seizure disorder, and migraine and its variants. However, underlying unusual pathophysiological processes such as brain tumors can also cause transient neurological dysfunction.

What are transient neurological deficits?

The American Heart Association/American Stroke Association definition of TIA was used: brief episode of neurologic dysfunction caused by focal brain, spinal cord, or retinal ischemia, with clinical symptoms typically lasting less than 1 hour and without evidence of acute infarction.

What are examples of neurological symptoms?

Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness.

How do you know if you have a neurological disorder?

Physical symptoms of neurological problems may include the following:

1. Partial or complete paralysis.
2. Muscle weakness.
3. Partial or complete loss of sensation.
4. Seizures.
5. Difficulty reading and writing.
6. Poor cognitive abilities.
7. Unexplained pain.
8. Decreased alertness.

What body system does a TIA affect?

A transient ischemic attack (TIA) happens when blood flow to part of the brain is blocked or reduced, often by a blood clot. After a short time, blood flows again and the symptoms go away. With a stroke, the blood flow stays blocked, and the brain has permanent damage.

What are normal symptoms after transient global amnesia?

Sudden onset of memory loss,verified by a witness

Retention of personal identity despite memory loss

Normal cognition,such as the ability to recognize and name familiar objects and follow simple directions

Absence of signs indicating damage to a particular area of the brain,such as limb paralysis,involuntary movement or impaired word recognition

How do neurologists diagnose transient ischemic attack?

Neurologists were more likely to diagnose transient ischemic attack based on clinical features including negative symp- toms or speech deficits. Patients with positive symptoms, altered level of consciousness, or the presence of nonfocal symptoms such as confusion or amnesia were more lik ely to be diagnosed with transient ischemic attack–mimic.

Can a TIA cause syncope?

Stroke (bleeding in the brain) can cause syncope associated with headache. Transient ischemic attack (TIA or mini-stroke) can cause fainting, usually preceded by double vision, loss of balance, slurred speech, or vertigo (a spinning sensation).

Can transient ischemic attack TIA cause seizures?

Several studies have investigated the frequency of epileptic seizures following ischemic strokes and transient ischemic attacks (TIAs). Little attention has been paid to the possibility that seizures may be precipitated by TIAs. We examined if seizures can be the only symptom of a TIA and how often this might occur.
