Headache or head pain is a very common symptom. It is often without cause, although some brain and blood vessel abnormalities can be causative and may need to be excluded.
This can be a wide ranging problem, from light-headedness, to spinning, to imbalance (such as feeling like you are rocking on a boat). There are a number of causes that can be examined.
Fits, Faints and Funny turns
A loss of consciousness may be related to lack of blood flow to the brain (syncope or fainting) or to abnormal electrical activity in the brain (seizure). The propensity to have recurrent seizures is called epilepsy.
Stroke (also known as cerebrovascular disease) occurs when the supply of blood to the brain is suddenly disrupted. Blood is carried to the brain by blood vessels called arteries. Blood may stop
moving through an artery because the artery is blocked by a blood clot or plaque, or because the artery breaks or bursts.
A peripheral nerve, or simply nerve is an enclosed, cable-like bundle of many peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves can be damaged due to pressure or trauma, or due to immune attack or toxins or vitamin deficiency (among others).
Tremor and Problems with Movement
Tremor is movement of a body part (often hands, occasionally legs, neck or face) which is not under voluntary control. Moving can also be affected, such as slowness of difficulty.
