Alzheimer’s Disease
A condition characterized by unease and fear.
Symptoms of Anxiety can be treated with benzodiazepines
Anxiety
A behavior disorder, usually in young children, characterized by inattentiveness, hyperactivity, and impulsiveness.

A condition characterized by irregular, alternating periods of mania and depression
Bipolar Disorder
A condition of slowed movement.
Bradykinesia
A prolonged state of unconsciousness with no response to stimuli.
Coma
A slow, progressive deterioration of the brain affecting everyday activities (memory, thinking, alertness, reasoning).
Dementia
A mood disorder characterized by a lack of cheerfulness, dejection, loss of hope, and a lack of interest in daily activities.
Depression
A disorder of the brain resulting in seizures. There are two types of seizures: partial and generalized.
Epilepsy
Consist of absence (petit mal), myoclonic, tonic-clonic, akinetic, and status epilepticus seizures.
Generalized sesures
A condition characterized by the inability to sleep, usually caused by depression, pain, or excessive caffeine intake.
Insomnia
A mental state characterized by excessive excitement and feelings of grandeur.
Mania
Inflammation of the membranes covering the CNS, (brain, spinal cord), characterized by neck stiffness, headache, altered mental status, and fever, usually caused by bacteria.
Meningitis
Severe headaches which are associated with nausea or light and sound sensitivity or both.
migraines
A chronic, progressive degeneration of the CNS that can result in decreased stimulation, paralysis, shakiness, and speech abnormalities.
Multiple sclerosis
An autoimmune disorder that affects the transmission of nerve impulses throughout the body, resulting in a weakness of the skeletal muscles.
Myasthenia gravis
Syndrome characterized by uncontrolled drowsiness and sleepiness.
Narcoolepsy
Any disease of the nervous system.
neropathy
A condition characterized by persistent ideas, thoughts, or images causing anxiety and distress along with corresponding behaviors designed to reduce anxiety or stress, such as repeated handwashing.
Obsessive-compulsive disorder
An anxiety disorder in which the patient experiences recurrent attacks.
Panic disorder
A progressive, degenerative CNS disorder characterized by constant muscle spasms and shakiness.
Parkinson’s disease
Seizures that occur in only part of the brain, characterized by muscle contractions followed by relaxation
partial sesures
An anxiety disorder characterized by a general fear of a situation.
Phobia
A neurological condition that results when nerves throughout the body are not working properly, resulting in a loss of feeling or weakness.
polyneropathy
A neurological condition that results when nerves throughout the body are not working properly, resulting in a loss of feeling or weakness.
posttraumatic stress disorder
A psychotic disorder characterized by separation from reality, usually accompanied by abnormal behavior, illogical thinking, and hallucinations.
Schizophrenia
Also known as a CVA (cerebrovascular accident); is damage to the brain caused by either a blockage of blood supply to the brain or hemorrhage in the brain.
Stroke
The Nervous System can be divided into two parts:
Central nervous system
Peripheral nervous system
The CNS, Central Nervous System consists of the
Brain and spinal cord
lies outside of the CNS and links the rest of the body to the CNS through a network of nerves that carry impulses to and from the brain and spinal cord.
Peripheral nervous system
functions when the body is under stress resulting in fight or flight syndrome.
sympathetic nervous system
functions when the SNS is not active and is sometimes referred to as the rest-and-digest system.
Parasympathetic system
are neurotransmitters found in the SNS.
Norepinephrine and epinephrine
is the main neurotransmitter in the PNS.
Acetylcholine
A medication that decreases the body’s sensitivity to pain or touch.
Anesthetic
A medication designed to prevent seizures or convulsions.
Anticonvulsant
A medication designed to prevent or relieve depression.
antidepressive
A medication used to treat severe psychiatric disorders.
antipsychotic
A medication class that depresses the CNS, resulting in calmness or sleep.
Barbiturate
Root word meaning head.
Cephal
is a clear, watery fluid produced by the brain that helps cushion the brain and spinal cord from injury.
Cerebrospinal fluid
A hormonal neurotransmitter released by the brain that is involved in various functions (attention, memory, learning, emotional arousal, rewarding sensations).
Dopamine
The process of graphing the electrical activity of the brain.
Electroencepholography
The process of graphing the electrical activity of the brain.
Electroencephalography
Root word meaning brain.
Encephal/o
Root word meaning nerve.
Nerv/o Nerv/i Neur/o Neur/i
A fibrous group of neurons that connect the brain or spinal cord to other parts of the body.
Nerve
A specialized impulse-conducting cell that is the functional unit of the nervous system that forms nerves.
Neuron
A medication that depresses the CNS, resulting in calmness or sleep.
Sedative
(5-HT): A hormonal neurotransmitter released by the brain involved in various functions (mood, pain perception, sleep, appetite, maintaining normal body temperature, hormonal state).
Serotonin
Anything that excites or activates a nerve.
Stimulus
