ADD/ADHD- Attention deficit disorder (ADD)/ attention deficit with hyperactivity disorder (ADHD) may be characterized by difficulty with the following: paying attention, concentrating, following directions, learning, keeping still, and completing tasks. Children with these disorders may be inclined to make impulsive decisions without stopping to think about the consequences of their choices. The disorder has three subtypes: inattentive, hyperactive-impulsive, and combined.

Clinical neurophysiology - This medical specialty studies the central and peripheral nervous systems through the recording of bioelectrical activity.

Developmental disorders - These disorders interfere with a child's development or acquisition of basic skills. There are many categories of developmental disorders. Specific developmental disorders affect a narrow area of development, such as a learning disability. Pervasive development disorders, such as autism, may affect a child's development overall. An example is the autism spectrum disorders, which affect a child's acquisition of communication and social skills, sensitivity to sensory stimulation, and other areas. Children with developmental disorders vary widely in their abilities, intelligence, and needs.

EEG - Electroencephalography (EEG) measures the activity of neurons in the brain using electrodes attached to the head. It is useful in diagnosing epilepsy, coma, encephalopathy and other brain disorders.

Electrodiagnosis - Recording electrical activity of the brain and nerves, such as with EEG, to diagnose illness and injuries.

Epilepsy - A neurological disorder characterized by seizures.

Guillain Barré syndrome - An acute autoimmune disease of the peripheral nervous system. There are six types of GBS each with unique symptoms involving muscle weakness, paralysis and other symptoms.

Hydrocephalus - A condition in which cerebrospinal fluid builds up in the ventricles, or cavities, of the brain. The head may swell and intracranial pressure may build, resulting in headache, nausea, sleepiness, coma, brain damage, or seizures.

Multiple Sclerosis (MS) - Multiple sclerosis is a chronic, often disabling disease that attacks the central nervous system (CNS), which is made up of the brain, spinal cord, and optic nerves. Symptoms may be mild, such as numbness in the limbs, or severe, such as paralysis or loss of vision.

Niedermeyer's Electroencephalography 6/e - The EEG in congential malformations of cortical development, neurocutaneous disorders, cerebral palsy, autism/mental retardation, and ADHD 

Neuro-oncology - This medical subspecialty deals with cancers of the nervous system and spine.

Neuroradiology - This medical field focuses on the diagnosis and treatment of brain, spinal cord, vascular, and head and neck lesions or tumors using x-rays, magnetic fields, radio waves, and ultrasound
