Silent Symptoms of a Stroke
However, there are also "silent" symptoms of stroke that may not be immediately obvious but can still indicate that a stroke is occurring. These silent symptoms include headache, vomiting and drowsiness. But these symptoms are also common in other medical conditions, so here we listing some sudden "silent" symptoms that may indicate possibility of a stroke.
- Sudden trouble walking or loss of balance and coordination
- Sudden memory loss or confusion
- Sudden changes in vision or perception
- Sudden tingling or weakness in the face, arm, or leg, especially on one side of the body
It's important to be aware of these silent symptoms of stroke, as prompt treatment can greatly improve outcomes and reduce the risk of permanent damage. If you experience any of these symptoms, seek medical attention immediately.
Understanding Stroke
Stroke is caused due to a blocked artery or the bursting of a blood vessel in the brain. The interruption of blood flow deprives the brain of oxygen and nutrients, which can cause brain cells to die and result in permanent brain damage.
There are two main types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic strokes are the most common, accounting for about 87% of all strokes. They occur when a blood clot or plaque blocks an artery that supplies blood to the brain. Hemorrhagic strokes, on the other hand, occur when a blood vessel in the brain ruptures and spills blood into the surrounding tissue.
Balance Problem during Stroke
Balance problems during a stroke can occur due to damage to the parts of the brain that control balance and coordination. The inner ear, which helps control balance, and the cerebellum, which is responsible for coordinating movement, can be affected by a stroke. If these areas of the brain are damaged, it can result in a loss of balance, making it difficult to stand or walk. Damage to the motor cortex, which controls voluntary muscle movements, can result in weakness or paralysis on one side of the body. This can cause an imbalance, making it difficult to stand or walk without assistance.
Memory Loss or Confusion during Stroke
Memory loss or confusion during a stroke can occur because of damage to the parts of the brain responsible for memory and cognitive function. The brain's memory centers, such as the hippocampus, can be affected by a stroke, causing difficulty with short-term memory or the ability to recall recent events. Confusion during a stroke can occur because of damage to the parts of the brain responsible for attention, perception, and executive function, such as the frontal lobe. This can result in disorientation, confusion, and difficulty with decision-making and problem-solving.
Changes in Vision or Perception during Stroke
The occipital lobe, which is responsible for processing visual information, can be affected by a stroke, causing vision changes such as double vision, blurriness, or temporary vision loss in one or both eyes. Damage to the parts of the brain responsible for perception and spatial awareness, such as the parietal lobe, can result in confusion about the location of objects or one's own body, as well as difficulty with spatial orientation and perception of size and distance.
Weakness in one side of body during Stroke
Weakness on one side of the body during a stroke can occur because of damage to the motor cortex, which controls voluntary muscle movements. If the blood supply to this area of the brain is disrupted, it can result in weakness or paralysis on one side of the body. This is known as hemiparesis or hemiplegia. The extent of weakness or paralysis can vary depending on the location and severity of the stroke. In some cases, only the face, arm, or leg may be affected, while in other cases, the entire side of the body may be weak or paralyzed.
Stroke is a leading cause of death and disability worldwide. Quick recognition of symptoms and prompt treatment can greatly improve outcomes and reduce the risk of permanent damage. Treatment may include medications to dissolve blood clots, surgery to remove blockages, or rehabilitation to help regain lost functions. In some cases, lifestyle changes such as quitting smoking, eating a healthy diet, and getting regular exercise can help reduce the risk of stroke.
