Study Notes
Symptoms of Neurological Disorders
- Advanced Multiple Sclerosis (MS) symptoms include significant motor impairment and cognitive difficulties.
- Alzheimer's disease symptoms encompass memory loss, confusion, and difficulty with language.
Risk Factors and Causes
- The most established risk factor for MS is a combination of genetic predisposition and environmental factors.
- Huntington's disease is caused by a genetic mutation in the HTT gene, leading to neurodegeneration.
Epilepsy and Parkinson's Disease Models
- The kindling model of epilepsy involves repeated subthreshold stimulation to induce seizures.
- The MPTP model of Parkinson's disease is used to study the effects of dopamine depletion and evaluate potential therapies.
Sensory Deafferentation Effects
- In adult macaques, sensory deafferentation can lead to functional reorganization of the brain and altered perception.
Brain Tumor Types
- Diffuse brain tumors grow infiltratively through surrounding brain tissue.
- Gliomas originate from glial cells and can exhibit aggressive behavior.
- Meningiomas arise from the meninges, are often encapsulated, and generally benign.
Brain Injury Terminology
- An area of dead or dying tissue surrounded by a penumbra is referred to as an infarct.
- An injury that includes bleeding without laceration, leading to a hematoma, is classified as a contusion.
- A concussion is termed as a blow to the head that causes disruption of consciousness.
Neural Circuit Reorganization
- Proposed mechanisms for neural circuit reorganization after damage include collateral sprouting and dendritic arborization.
Challenges and Benefits of Recovery
- One challenge in studying recovery post-CNS damage is variability in individual responses and types of injuries.
- Rehabilitative training promotes recovery by enhancing neural plasticity and functional reorganization within the brain.
Neurotransplantation Insights
- Implants used in neurotransplantation can stimulate neuronal growth and integration into existing neural circuits.
- Stem cells have potential to differentiate into various cell types and promote healing in damaged brain areas.
Enriched Environments and Recovery
- Exposure to enriched environments can lead to improved cognitive and motor outcomes following CNS damage by enhancing learning and neuroplasticity.
Epilepsy and Chronic Traumatic Encephalopathy (CTE)
- A key characteristic of epilepsy is the occurrence of recurrent seizures.
- Chronic traumatic encephalopathy (CTE) is primarily caused by repeated head trauma.
Multiple Sclerosis Research Focus
- Current MS research concentrates on understanding immune responses, potential disease-modifying therapies, and neuroprotective mechanisms.
Functions and Cellular Processes
- Oligodendrocytes are responsible for producing myelin in the central nervous system, crucial for proper neuronal function.
- Apoptosis is a controlled cell death process, whereas necrosis is an uncontrolled cell death often resulting from injury.
Treatment for Epilepsy
- Treatments for epilepsy may include antiepileptic drugs, lifestyle modifications, and in some cases, surgical interventions.
