Neurology is the treatment and management of the nervous system and the disorders of this complex part of the body. Components of the neurological examination include assessment of the patient's cognitive function, cranial nerves, motor strength, sensation, reflexes, coordination, and gait. In some instances neurologists may order additional diagnostic tests such as computed axial tomography (CAT) scans, magnetic resonance imaging (MRI), and ultrasound of major blood vessels of the head and neck. Neurophysiologic studies, including electroencephalography (EEG), electromyography (EMG), and evoked potentials are also commonly ordered.
Some of the commonly encountered conditions treated by neurologists include:
- Seizures and epilepsy
- Parkinson's Disease
- Multiple sclerosis
- Head trauma
- Sleep disorders
- Neuromuscular diseases
- Various infections and tumours of the nervous system.
