Define: Dysarthria | A motor speech disorder resulting from neurological injury that affects the physical production of speech, leading to slurred or slow speech. His dysarthria made it difficult for others to understand him. |
Define: Ataxia | A neurological sign consisting of lack of voluntary coordination of muscle movements, leading to unsteady gait and difficulty with balance. The patient displayed ataxia, making it hard for him to walk steadily. |
Define: Paresis | A condition characterized by partial loss of voluntary movement or weakness in a muscle or group of muscles. He experienced paresis in his right arm after the stroke. |
Define: Paralysis | Loss of the ability to move one or more muscles, often resulting from injury or disease affecting the nervous system. Paralysis of her legs made it necessary for her to use a wheelchair. |
Define: Hemiparesis | Weakness on one side of the body, often resulting from a stroke or other neurological condition. He was diagnosed with hemiparesis after his stroke impacted his right side. |
Define: Hemiplegia | Complete paralysis of one side of the body, typically resulting from a stroke or brain injury. Hemiplegia left her unable to move her left arm and leg after the accident. |
Define: Paraplegia | Paralysis of the lower half of the body, typically affecting both legs, often due to spinal cord injury or disease. He faced paraplegia following the car accident that damaged his spine. |
Define: Quadriplegia | Paralysis that affects all four limbs, usually resulting from severe spinal cord injury or disease. After the fall, she was diagnosed with quadriplegia and required extensive rehabilitation. |
Define: Paresthesia | An abnormal sensation in the skin, such as tingling, prickling, or numbness, often caused by nerve damage or compression. He reported paresthesia in his fingers after sitting in one position for too long. |
Define: Hypesthesia | Reduced sensitivity to stimulation, often resulting from nerve damage or neurological conditions. The patient experienced hypesthesia in her feet, making it difficult to feel the ground. |
Define: Hyperesthesia | Increased sensitivity to sensory stimuli, which can lead to discomfort or pain in response to normal sensations. His hyperesthesia made even light touches feel painful. |
Define: Nystagmus | Involuntary eye movements that can lead to reduced vision and depth perception, often associated with neurological conditions. The neurologist noted nystagmus during the eye examination. |
Define: Diplopia | The perception of two images of a single object, commonly known as double vision, often resulting from neurological or muscular disorders. He complained of diplopia after the head injury. |
Define: Anosmia | The loss of the sense of smell, which can occur due to nasal obstructions, neurological conditions, or head trauma. Her anosmia made it difficult for her to enjoy food after the accident. |
Define: Dysphagia | Difficulty swallowing, which can result from various medical conditions affecting the throat or esophagus. He was evaluated for dysphagia after choking on food. |
Define: Vertigo | A sensation of spinning or dizziness, often caused by problems in the inner ear or brain, affecting balance. She experienced vertigo after standing up too quickly. |
Define: Syncope | A temporary loss of consciousness and muscle strength, commonly known as fainting, often due to insufficient blood flow to the brain. His syncope occurred while he was standing in line, leading to a fall. |
Define: Tremor | Involuntary, rhythmic muscle contractions leading to shaking movements in one or more parts of the body, often associated with neurological disorders. She noticed a tremor in her hands when trying to hold a cup. |
Define: Bradykinesia | Slowness of movement, commonly seen in conditions like Parkinson's disease, affecting the ability to initiate and perform voluntary movements. He exhibited bradykinesia, making his movements appear sluggish. |
Define: Rigidity | Increased muscle tone and stiffness, often associated with neurological conditions such as Parkinson's disease, leading to reduced flexibility. The examination revealed rigidity in her arms and legs. |
Define: Spasticity | A condition characterized by abnormal muscle tightness due to prolonged muscle contraction, often seen in neurological disorders. His spasticity made it difficult for him to move his legs freely. |
Define: Clonus | A series of involuntary muscle contractions and relaxations, often occurring in response to sudden stretching of the muscle, commonly seen in neurological disorders. The doctor observed clonus in his ankle during the neurological examination. |
Define: Babinski Sign | A reflex action in which the big toe extends upward when the sole of the foot is stimulated, indicating neurological function and development. The presence of a positive Babinski sign in adults can indicate neurological damage. |
Define: Reflex (Deep Tendon Reflexes) | Involuntary muscle contractions in response to a stimulus, often tested to assess the integrity of the nervous system. The doctor checked his deep tendon reflexes to evaluate neurological function. |
Define: Gait Disturbance | A change in the normal walking pattern, which can result from neurological disorders, injuries, or other medical conditions. She exhibited gait disturbance after her stroke, making walking difficult. |
