What do you mean By Delirium, and what are the Causes?

Delirium is one type of nervous system or a neurological condition or can also be defined as a severe disturbance in people’s mental abilities that can lead to mental confusion and emotional disruption. If you are suffering from this mental condition, you may find it challenging to think, remember, pay attention, sleep, and more.

In some cases, you may witness delirium after surgery, with dementia, or during alcohol withdrawal. This condition can be caused due to different factors, for example, exposure to particular medications, older age, surgery or different medical procedures, alcohol abuse, and more. However, it may be noted that this mental condition is generally temporary and can be treated correctly.

  • Physical and neurological exams

The doctor will carry out a physical exam to check the signs of health problems or underlying disease.  Besides, a neurological exam will also be conducted to check the vision, balance, coordination, and reflexes. With this, they can identify if a stroke or other mental conditions are causing the issue.

  • Mental status assessment

This can be carried out informally with the help of conversation or by screenings that can effectively assess the current mental condition, memory, or perception. Besides, the doctor may seek a few additional information from the caregivers or family members.

  • Some other tests

Under this, your doctor may conduct an order for urine, blood, and other diagnostic tests. In some cases, the doctor can conduct a brain-imaging test when the diagnosis cannot be performed with other available information.
