Neurological Conditions

Neurological Conditions

The brain, spinal cord, and nerves make up the nervous system. Together they control all the workings of the body. When something goes wrong with a part of your nervous system, you can have trouble moving, speaking, swallowing, breathing, or learning. You can also have problems with your memory, senses, or mood.

Overview

There are more than 600 neurologic diseases. Major types include:

  • Diseases caused by faulty genes, such as Huntington's disease and muscular dystrophy.
  • Problems with the way the nervous system develops, such as spina bifida.
  • Degenerative diseases, where nerve cells are damaged or die, such as Parkinson's disease and Alzheimer's disease.
  • Diseases of the blood vessels that supply the brain, such as stroke.
  • Injuries to the spinal cord and brain.
  • Seizure disorders, such as epilepsy.
  • Cancer, such as brain tumors.
  • infections, such as meningitis.

Some of these can be treated with infusion therapy.

Symptoms

The signs of neurological disorders can vary significantly, depending upon the type of disorder as well as the specific area of the body that is affected. In some instances, you might experience emotional symptoms while in other cases physical symptoms may be the result. Some of the symptoms include:

Emotional - mood swings or sudden outbursts. Individuals who suffer from neurological problems may also experience depression or delusions.

Physical -

  • Partial or complete paralysis.
  • Muscle weakness.
  • Partial or complete loss of sensation.
  • Seizures.
  • Difficulty reading and writing.
  • Poor cognitive abilities.
  • Unexplained pain.
  • Decreased alertness.

Causes

The causes of neurological dysfunction can be quite diverse. Both the spinal cord and brain are insulated by numerous membranes that can be vulnerable to force and pressure. The peripheral nerves located deep under the skin can also be vulnerable to damage. Neurological disorders can affect an entire neurological pathway or a single neuron. Even a small disturbance to a neuron’s structural pathway can result in dysfunction. As a result, neurological disorders can result from a number of causes, including:

  • Lifestyle related causes.
  • Infections.
  • Genetics.
  • Nutrition-related causes.
  • Environmental influences.
  • Physical injuries.

Diagnosis

Apart from a physical and physiological test, there are specialized tests that can be done diagnostically.

  • CT or CAT scan - A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
  • Electroencephalogram (EEG) - A procedure that records the brain's continuous electrical activity through electrodes attached to the scalp.
  • Magnetic resonance imaging (MRI) - A diagnostic procedure that uses a combination of large magnets, radio frequencies, and a computer to produce detailed images of organs and structures within the body.
  • Electromyography (EMG) and nerve conduction velocity (NCV) - Studies that evaluate and diagnose disorders of the muscles and motor neurons. Electrodes are inserted into the muscle, or placed on the skin overlying a muscle or muscle group, and electrical activity and muscle response are recorded.
  • Positron emission tomography (PET) - In nuclear medicine, a procedure that measures the metabolic activity of cells.
  • Arteriogram (also called an angiogram) - An X-ray of the arteries and veins to detect blockage or narrowing of the vessels.
  • Spinal tap (also known as lumbar puncture) - A special needle is placed into the lower back, into the spinal canal. This is the area around the spinal cord. The pressure in the spinal canal and brain can then be measured. A small amount of cerebrospinal fluid (CSF) can be removed and sent for testing to determine if there is an infection or other problems. CSF is the fluid that bathes the brain and spinal cord.
  • Evoked potentials - Procedures that record the brain's electrical response to visual, auditory, and sensory stimuli.
  • Myelogram - A procedure that uses dye injected into the spinal canal to make the structure clearly visible on X-rays.
  • Neurosonography - A procedure that uses ultra high-frequency sound waves that enable the healthcare provider to analyze blood flow in cases of possible stroke.
  • Ultrasound Imaging - A diagnostic imaging technique that uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs.

Treatment

Apart from the issue of a cure, sometimes patients with neurological issues can be placed in rehabilitation as part of an effort to restore some lost function. This is usually a hopeful sign, as it’s rare to find a patient assigned to therapy when there’s little to no hope of at least a partial recovery. Therapies for neurological disorders may often consist of:

  • Lifestyle changes to either prevent or minimize the impact of such conditions.
  • Physiotherapy to manage the symptoms and restore some function.
  • Pain management, as many impairments can be associated with considerable discomfort.
  • Medication to either restore function or prevent a worsening of the patient’s condition.

Medication

These may range from medications such as the neuroleptics (haloperidol and chlorpromazine) used to treat organic disorders of the brain such as schizophrenia, to comparatively simple analgesics, such as ibuprofen, acetaminophen and opiates to treat the painful effects of many neurological ailments.
