Symptom

Confusion

Confusion refers to a state in which a person's thinking, attention and awareness are disturbed. The symptom may appear, for example, as difficulty understanding the surroundings, a clouding of awareness of time and place, memory difficulties or restlessness. Confusion can develop suddenly and may be accompanied by hallucinations or muddled speech. Typically, relatives notice the change in a person's behaviour quickly.

The most common causes of confusion in Finland are various physical illnesses, such as infections (for example pneumonia or a urinary tract infection), cerebrovascular disorders, dehydration, low blood sugar, or the sudden stopping of intoxicant use, especially alcohol. In older adults, confusion is often a sign of an organic disorder. Confusion can also be a side effect of medication. The symptom should not be ignored, as there may be a serious illness behind it. What makes confusion especially concerning is its sudden onset, a concurrent fever or severe confusion, in which case it is advisable to seek care quickly.
