Mini-Strokes Often Go Unnoticed: 9 Symptoms You Should Never Ignore
* Stagger
* Walk unusually
* Drop objects
* Have difficulty coordinating a hand or arm
* Need support to remain standing
Balance loss is important enough to be included in the **B.E. F.A.S.T.** stroke-recognition method.
Any sudden and unexplained loss of coordination deserves emergency attention.
## 8. Sudden Confusion
A TIA may temporarily affect the ability to think clearly or understand information.
A person might:
* Appear unusually confused
* Give strange answers
* Have difficulty following instructions
* Not understand what is being said
* Suddenly seem disoriented
The NHS includes confusion and difficulty understanding others among possible TIA symptoms.
A sudden change in mental status should never simply be attributed to tiredness or aging.

It is particularly concerning when accompanied by:
* Weakness
