Mental confusion (often simply called confusion) is a symptom. People suffering from it have problems finding their way around in the world. They have troubles remembering who they are, where they are, or what time (or day of the week) it is. Additionally, they may have trouble remembering things or memorizing new things. This may be linked to problems focusing their attention. Confusion can also be a sign of someone being sick with various illnesses when it's coupled with things like fever, chills, or exhaustion.
Medical causes of confusionEdit
Confusion can be caused by many different medical problems.
Acute causes of confusionEdit
Acute causes of confusion usually come on suddenly, and doctors may be able to fix some of them.
- Alcohol (being drunk) or Acidosis (having too much acid in the blood, which poisons the body)
- Environmental causes (like being very cold) or Epilepsy (being confused after a seizure)
- Infection (like meningitis, an infection of the brain's lining)
- Overdose (taking too much medicine or too many illegal drugs)
- Uremia (poisons building up in the blood because of kidney problems) or Underdose (not taking enough prescribed medicine)
- Trauma (injury, especially to the head)
- Insulin (confusion because of a blood sugar emergency - blood sugar is either too low or much too high)
- Psychogenic (when mental illness causes confusion)
- Stroke (when not enough blood and oxygen gets part of the brain)
- Low blood pressure (when the heart is not pumping hard enough to get blood and oxygen to the brain)
- If the heart is beating too slow, or too fast, or not regularly (making the heart unable to get blood and oxygen up to the brain)
- A breathing problem that makes it impossible to get enough oxygen into the body (like a bad asthma attack, or chronic obstructive pulmonary disease (COPD))
Chronic causes of confusionEdit
Chronic causes of confusion usually come on less suddenly and last for a long time (months or years). For example:
