Root Word
What does the root word psycho/o mean?
Mind
A chronic neurological disorder caused by the brain's inability to regulate sleep-wake cycles effectively, leading to excessive daytime sleepiness, sudden "sleep attacks," and sometimes sudden muscle weakness (cataplexy).
Narcolepsy
A mental process that causes a lack of connection in a person's thoughts, memories, sense of identity, or perception of the environment. It can range from mild, everyday experiences like daydreaming to severe disruptions as a coping mechanism for trauma, leading to disorders like dissociative identity disorder.
Dissociation
The suffix -orexia means?
Appetite
A neurological condition, typically from stroke or brain injury, that impairs language, affecting the ability to speak, understand speech, read, or write.
Aphasia
This root word crani/o means?
Cranium
Chronic neurological disorder of the brain characterized by an enduring predisposition to generate recurrent, unprovoked seizures. A seizure is a sudden, transient episode of abnormal excessive or synchronous neuronal activity in the brain, which can cause involuntary movements, behavior changes, or a loss of awareness. It is a spectrum condition, and symptoms can vary widely in type and severity.
Epilepsy
disorder in which a person eats large amounts of food (“bingeing”) and then rids the body of that food before it can be absorbed (“purging”)
Bulimia
I am a suffix -esthesia, what does this mean?
Sensation or perception
A severe inability to swallow food or liquids, leading to potential choking or aspiration, often caused by neurological damage or muscle weakness.
Aphagia
What does the root word myel/o mean?
Bone marrow or spinal cord
Group of non-progressive neurological disorders that appear in early childhood and affect a person's ability to move, maintain balance, and posture. It is caused by abnormal brain development or damage to the developing brain that occurs before, during, or shortly after birth. Symptoms vary and can range from mild awkwardness in walking to needing lifelong care, but the brain damage itself does not worsen over time.
Cerebral Palsy
Actions that violate social norms and the personal or property rights of others. It exists on a severity continuum and can include covert hostility (theft, vandalism) or overt aggression (bullying, fighting), characterized by a lack of remorse or disregard for others' feelings.
Antisocial Behavior
I am a root word that means neck or sometimes cervix, what am I?
Cervic/o
What are the two main divisions of the nervous system?
Autonomic and Somatic
What does the root word cerebr/o or encephal/o mean?
Brain
chronic autoimmune neuromuscular disease. In this disorder, the body's immune system mistakenly produces antibodies that attack healthy cells, specifically nicotinic acetylcholine receptors at the neuromuscular junction, which are needed for normal muscle function. This leads to fluctuating muscle weakness that worsens with activity (fatigable muscle weakness), commonly affecting the voluntary muscles of the eyes (causing drooping eyelids and double vision), face, throat, and limbs.
Myasthenia Gravis (MG)
Paralysis affecting corresponding parts on both sides of the body, most commonly the legs, though arms can also be involved.
Diplegia
What does the root word physi/o mean?
Nature
Condition in which fluid accumulates in the brain, typically in young children, enlarging the head and sometimes causing brain damage
Hydrocephalus
What does the root word phren/o mean?
Mind or Diaphragm
A bruise of the brain tissue involving localized bleeding from small blood vessels into the brain tissue itself. It is a more serious structural injury than a concussion and is often caused by the brain striking the sharp ridges inside the skull during a forceful impact. Contusions can cause swelling (edema), which may increase pressure inside the skull and lead to permanent damage if severe.
Cerebral Contusion
Softening or loss of brain tissue, typically as the end result of liquefactive necrosis following injury such as a stroke (infarction), hemorrhage, or trauma.
Encephalomalacia
This is the technique or process of recording the electrical activity of the brain.
Electroencephalography (EEG)
Refers to the inability to initiate movement or the complete absence of movement. It can manifest as delayed response, episodes of freezing mid-action (such as freezing of gait), or a lack of spontaneous or associated movements like blinking or arm swinging while walking.
