can someone explain the following:
ischaemia in the brain.
can this also mean a minor stroke?
Or can it lead to a stroke?
Is this related to dementia?

Ischemia means restricted blood flow, commonly due to a narrowed blood vessel. This means that part of the brain is potentially not getting its full suppy of blood.
If the vessel is narrowed there is a highher risk of it becoming blocked completly by a blood clot, this is known as a stroke, as part of the brain is deprived of blood and oxygen for a period of time. However the amount of risk is dependent on the severity of the narrowing of the vessels.
Depending on what part of the brain is being supplied by the narrowed blood vessel and the amount restriction to blood flow the type of symptoms experienced, severity of symptoms and risk of stroke will also vary.
As to the case of the individual you are referring to in your question this is best answered by a neurologist who has reviewed the results of the patients MRI scan and will be able to give appropriate advice and treatment.

Ischemia is tissue death. This is usually caused by a blockage in the bloodflow that leads to that area, which leads to tissue death. Basically, no oxygen = death.
Yes, it can mean a minor stroke - however, it can also be normal changes due to aging.
In some cases, yes, it can be related to dementia.
Check with a specialist such a neurologist that can look at the MRI and give you a better opinion. (A general practitioner is not going to have the expertise needed to diagnose the condition.)

ischemia refers to a lack of blood flow. Ischemia in the brain usually results in a stroke, transient ischemic attacks, and yes dementia can result.

Now that you have all the real good stuff from all these good people that know how to read MRI's and are Technologists in the field, and your not shaking to bad of fright, call your doctor and ask him, he's the answer man.
