Study Notes
Neurological Disorders Overview
- Niemann-Pick disease is caused by sphingomyelinase deficiency leading to sphingomyelin accumulation in neurons, resulting in toxicity.
- Deficiencies of certain vitamins cause CNS lesions, including thiamine (vitamin B1), vitamin B12, and nicotinic acid (vitamin B3).
- Alcohol has profound effects on the brain, causing nutritional and metabolic disturbances, repeated head trauma, and direct atrophy.
- Neurodegenerative diseases, such as Alzheimer’s, Huntington’s, Parkinson’s, and ALS, affect specific parts of the brain and have unknown etiologies.
- Alzheimer’s disease is the most common cause of dementia in the elderly, leading to progressive impairment of cognitive and motor functions.
- Parkinson’s disease is a subcortical neurodegenerative disease characterized by decreased dopaminergic neurons in the substantia nigra and TRAP symptoms.
- Huntington disease is an autosomal dominant neurodegenerative disease caused by a mutation in the huntingtin (HTT) gene, leading to involuntary movements and progressive dementia.
- ALS, also known as Lou Gehrig’s disease, is a progressive and fatal motor neuron disease characterized by motor weakness and muscle wasting, leading to paralysis of respiratory muscles.
- The objectives of the text include describing the structure and function of the central nervous system, causes and symptoms of increased intracranial pressure, and classification of CNS trauma.
- Approximately 50% of CNS neoplasms are primary, with gliomas and meningiomas being common types.
- Gliomas are tumors arising from glial cells and can have different prognoses, with glioblastoma being highly aggressive and having a poor prognosis.
- Meningiomas are neoplasms arising from meninges, usually benign but potentially fatal if located in vital areas.
Central Nervous System (CNS) Trauma, Infections, and Diseases Overview
- The cervical spinal cord is the most vulnerable to injury due to its high mobility.
- CNS trauma can result in ligament rupture, spinal nerve compression, and spinal cord transection.
- CNS infections can be acquired through vascular spread, direct extension, or ascending neural route.
- Meningitis can be acute pyogenic (bacterial), aseptic (viral), or chronic (tuberculosis, fungal infections).
- Viruses such as HIV can cause encephalitis and impact the CNS, leading to AIDS-related encephalopathy.
- Prions are infectious protein particles that selectively infect the nervous system, causing diseases like Creutzfeldt-Jakob disease.
- Multiple sclerosis is an autoimmune demyelinating disease with a chronic relapsing and remitting course.
- Its pathology involves white matter demyelination, leading to sensory and motor symptoms.
- CNS metabolic diseases include inborn errors of metabolism like Tay-Sachs and Niemann-Pick disease.
- Tay-Sachs disease results from Hexosaminidase A deficiency and primarily affects infants under 6 months of age.
- CNS trauma, infections, and diseases are important to understand for their impact on the structure and function of the central nervous system.
- Understanding the causes, symptoms, and clinical presentations of these conditions is essential for effective diagnosis and treatment.
