What are neurocognitive disorders?

Neurocognitive disorders are a category of disorders that often result in impaired mental function. Organic brain syndrome was once the term for these disorders, but neurocognitive disorders is now the more common term.

Neurocognitive disorders most often occur in older adults, but they may occur in younger people. Declines in mental function may include:

• Difficulty remembering things
• Changes in personality or behavior
• Problems with communication
• Difficulty carrying out daily activities

These symptoms might come from a neurodegenerative condition, like Alzheimer's disease or dementia. Neurodegenerative disorders result in a loss of neurological function as the brain and nerves deteriorate over time. Additionally, substance misuse or brain damage might result in neurocognitive problems. Medical professionals may usually identify the fundamental cause of neurocognitive problems. From the reported symptoms and diagnostic results, the cause and nature of neurocognitive disorders will guide how patients should be treated.

What are some common symptoms of neurocognitive disorders?

The condition manifests in different ways in a patient, depending on the cause. If the condition is caused by a disease such as neurodegenerative illness, patients may have:

• Memory Loss
• Confusion
• Anxiety

Other symptoms experienced by people with neurocognitive disorders include:

• Headaches, especially by those who have a concussion or traumatic brain injury
• Inability to concentrate or focus
• Short-term memory loss
• trouble performing routine activities, such as driving
• Difficulty walking and balancing
• Changes in vision

What causes neurocognitive disorders?

The most frequent cause of neurocognitive disorders is a neurodegenerative disease. Neurodegenerative diseases can lead to problems with thinking and memory. Some of these diseases include:

• Alzheimer's disease
• Parkinson's disease
• Huntington's disease
• Dementia
• Prion disease
• Multiple sclerosis

In people younger than 60, cognitive issues are more often caused by injuries or infections. The following conditions can also bring on cognitive problems:

• A concussion
• Traumatic brain injury with bleeding in or around the brain
• Blood clots
• Meningitis
• Encephalitis
• Septicemia
• Drug or alcohol abuse
• Vitamin deficiency

What puts you at risk for neurocognitive disorders?

Your everyday routine and way of life are very important. These illnesses are more likely to occur if you work in an environment with heavy metals. Heavy metals, like lead and mercury, cause damage to the nervous system over time. Frequent exposure to these metals increases your risk for decreased mental function.

You also tend to be at greater risk for neurocognitive disorders if you:

• Are more than age 60
• Have a cardiovascular disorder
• Have diabetes
• Abuse alcohol or drugs
• Engage in sports involving significant risk of head trauma, like football and rugby

How are Neurocognitive Disorders diagnosed?

Neurocognitive disorders are not the result of a mental disorder. Still, several symptoms of neurocognitive disorders resemble those of certain mental disorders such as psychosis, schizophrenia, and depression. Thus, a healthcare provider may carry out several diagnostic tests to confirm an accurate diagnosis by differentiating symptoms of neurocognitive disorders from those of a mental disorder. Common tests include:

• Cranial CT scan uses a sequence of X-ray images to generate images of the skull, brain, sinuses, and eye sockets. It can also view the soft tissues in the brain.
• Head MRI scan: This radiology test uses strong magnets and radio waves to create detailed brain images. The images can show whether the brain has damage.
• Positron emission tomography (PET) scan: A PET scan uses a special dye that contains radioactive tracers. Doctors inject these tracers into a vein. They spread through the body and help identify damaged areas.
• Electroencephalogram (EEG): An EEG measures electrical activity in the brain. This test can detect any problems associated with this activity.

How are neurocognitive disorders treated?

Treatment for neurocognitive disorders depends on the cause of the condition. Some conditions only need rest and drugs, while neurodegenerative diseases may require other forms of therapy.

Some of the treatments for neurocognitive disorders include:

• Bed rest for injuries to heal
• Pain medications like indomethacin to cure headaches
• Antibiotics to clear residual infections that might be affecting the brain, such as meningitis
• Surgical intervention to repair severe brain damage
• Occupational therapy to regain the ability to use everyday skills
• Physical therapy to strengthen muscles, improve coordination, balance, and flexibility

What Is the Prognosis for Persons with Neurocognitive Disorders?

The prognosis depends on the particular neurocognitive disorder. Neurocognitive disorders, which include dementia or Alzheimer's, have a concerning prognosis. This is mainly because there are no treatments that reverse those conditions, and mental function worsens gradually over time.

However, people with neurocognitive disorders, such as a concussion or infection, generally have a good prognosis in that these are temporary, curable conditions. People can usually look forward to making a full recovery in such cases.
