Betz cells, also known as giant pyramidal cells, are large neurons found in the primary motor cortex of the brain. They are responsible for initiating voluntary muscle movements.
Betz cells are among the largest neurons in the human body, with long axons that extend down the spinal cord to connect with muscles throughout the body. They play a crucial role in the execution of precise and coordinated movements.
A stroke occurs when blood flow to part of the brain is interrupted, either by a blockage or the rupture of a blood vessel. This deprives the brain of oxygen and nutrients, causing brain cells to die.
Strokes can lead to a variety of symptoms depending on which part of the brain is affected and how severe the damage is. They can result in temporary or permanent disabilities, including paralysis, speech impairment, and cognitive deficits. Strokes require immediate medical attention as they can be life-threatening and cause long-term disability if not treated promptly.
Types of Stroke:
- Ischemic Stroke: Caused by a blockage in a blood vessel supplying the brain.
- Hemorrhagic Stroke: Caused by the rupture of a blood vessel, leading to bleeding in the brain.
Causes of Stroke:
- High blood pressure
- Smoking
- Diabetes
- High cholesterol
- Obesity
- Atrial fibrillation
- Sedentary lifestyle
- Family history of stroke
- Age (risk increases with age)
- Excessive alcohol consumption
- Drug abuse
- Poor diet
- Physical inactivity
- Heart disease
- Artery diseases
- Blood disorders
- Sleep apnea
- Stress
- Migraines
- Previous history of stroke or transient ischemic attacks (TIAs)
Symptoms of Stroke:
- Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body

- Seizures
- Fatigue
- Memory loss
- Personality changes
- Trouble with fine motor skills
- Slurred speech

- Carotid artery duplex
- Blood pressure monitoring
- Neurological examination
- Swallowing studies
- Carotid stenting
- Transesophageal echocardiogram (TEE)
- Holter monitor
- PET scan (Positron Emission Tomography)
- Angiogram
Non-Pharmacological Treatments for Stroke:

- Intracranial angioplasty and stenting
- Aneurysm clipping
- Aneurysm coiling (endovascular coiling)
- Craniotomy
- Ventricular shunt placement
- Decompressive craniectomy
- Thrombectomy
- Deep brain stimulation (DBS)
Preventive Measures for Stroke:
- Maintain a healthy weight
- Eat a balanced diet low in saturated fats, cholesterol, and sodium
- Exercise regularly
- Avoid smoking and limit alcohol consumption
- Manage chronic conditions such as high blood pressure, diabetes, and high cholesterol
- Control atrial fibrillation and other heart conditions
- Get regular check-ups and screenings
- Manage stress
- Get enough sleep
- Follow medication regimens as prescribed
When to See a Doctor:
Seek immediate medical attention if you or someone else experiences any signs or symptoms of stroke, even if they seem to go away. Time is critical in treating a stroke, and early intervention can minimize damage and improve outcomes.
