A treaty is an agreement between States (countries) which is binding at international law. In some cases international organisations can be parties to treaties. An agreement between an Australian State or Territory and a foreign Government will not, therefore, be a treaty.
The term mini-stroke refers to a transient ischemic attack (TIA for short). In a mini-stroke, there is a short-term interruption in blood flow to the brain. This causes temporary stroke symptoms (often just for a few minutes), such as weakness or tingling in an arm or leg. Mini-strokes do not cause brain damage, but they are important warning signs that a person is at risk of having a stroke.
A person who experiences a mini stroke of a similar size in the brainstem, an area of the brain which harbors the centers for gait balance, voice control, and eye movements, might feel temporarily unable to carry on with his or her day because of vertigo, difficulty speaking, or double vision.
