Stroke Symptoms: Sweating, Blackouts, And Jerks

Experiencing a blackout, excessive sweating, and jerking can be indicative of several serious health conditions, one of which is a stroke. A stroke occurs when blood flow to the brain is blocked or when a blood vessel bursts, resulting in brain cells becoming damaged or dying due to oxygen deprivation. While the specific symptoms you've mentioned could be indicative of a stroke, they could also be indicative of other conditions such as heat stroke, hypoglycaemia, or even epilepsy. It is important to seek immediate medical attention if you or someone you know is experiencing these symptoms, as quick treatment is crucial for survival and recovery.

Heat stroke is a life-threatening condition that can be caused by an inability to sweat

The body's natural cooling system can be overtaxed, leading to heat stroke. Normally, the body gets rid of excess heat through sweating, but if the air is very hot or the body is generating a lot of heat, it may struggle to keep up. This is especially dangerous for those with anhidrosis or hypohidrosis, conditions where the body cannot sweat normally or at all. These conditions can be caused by nerve damage, skin damage, certain medications, or inherited disorders.

The risk of heat stroke is higher for those over 65, pregnant women, dehydrated individuals, those with infections or cardiovascular disease, and those with conditions that limit their ability to sweat. Heat stroke can cause serious complications, including disruption to brain activity, muscle breakdown, reduced blood flow and oxygen to organs, and severe damage to vital organs. It requires immediate medical attention as it can lead to organ damage or even death.

While heat stroke typically occurs due to environmental or physical factors, an inability to sweat can be a contributing factor. This is because the body relies on sweating as a primary means of cooling itself, and without this function, the body's temperature can rise to dangerous levels. Therefore, an inability to sweat, combined with other factors, can increase the risk of heat stroke.

Blackouts can be caused by drinking large volumes of alcohol

Sweating, blackouts, and jerks can be symptoms of a variety of conditions, including alcohol intoxication, heat stroke, hypnic jerks, and epilepsy. While it is possible that these symptoms could be indicative of a stroke, there are many other potential causes.

There are two types of alcohol-related blackouts: fragmentary blackouts and total blackouts. Fragmentary blackouts, also known as "grayouts" or "brownouts," are characterized by gaps in memory combined with some recollection of events. On the other hand, total blackouts involve no recollection of events as the memories of what happened never form or cannot be accessed. This type of blackout can last for many hours.

Drinking a large volume of alcohol in a short period, also known as binge drinking, can cause a person's blood alcohol concentration to rise quickly, resulting in memory loss. Additionally, drinking on an empty stomach can also contribute to blackouts. While anyone who drinks large amounts of alcohol is at risk of blackouts, women tend to reach higher peak blood alcohol concentrations faster than men due to their lower body weight.

To prevent alcohol-induced blackouts, it is important to drink in moderation, avoid binge drinking, and refrain from mixing alcohol with other substances. Eating before and during alcohol consumption, drinking slowly, and alternating between alcoholic and non-alcoholic beverages can also help reduce the risk of blackouts.

Blackouts can be a symptom of epilepsy

Epilepsy is characterised by the tendency to have recurrent seizures without a clear physical trigger. It is usually diagnosed after two or more seizures, although it may occasionally be diagnosed after a single seizure if there is a high likelihood of another occurring. Common causes of epilepsy include inheriting certain genes or having an abnormality in the structure of the brain, often due to scarring from a previous injury, stroke, or infection.

Epileptic blackouts can be distinguished from other types of blackouts, such as those caused by alcohol consumption or syncope (fainting due to low blood pressure), through diagnostic testing. An electroencephalogram (EEG), for example, can reveal patterns of brain activity that indicate the likelihood of a seizure reoccurrence and help exclude conditions that mimic epilepsy.

It is important to seek medical attention if you experience blackouts, as they can be a sign of a serious underlying condition. While blackouts can be a frightening experience, treatment can enable individuals to lead a normal life without the fear of losing consciousness or memory.

Jerking movements can be a symptom of psychogenic blackouts

Experiencing jerking movements can be a symptom of psychogenic blackouts. A psychogenic blackout, also known as a psychogenic non-epileptic seizure (PNES), is defined by the American Academy of Family Physicians (AAFP) as:

> episodes of movement, sensation, or behaviours that are similar to epileptic seizures but do not have a neurological origin; rather, they are somatic (body-related) manifestations of psychological distress.

PNES are considered conversion or dissociative disorders, which occur when emotional suffering is expressed through physical symptoms. PNES are distinct from epileptic seizures in that they are not caused by neurological abnormalities but are instead related to psychological factors. PNES can be treated through psychotherapy, specifically cognitive behavioural therapy (CBT), prolonged exposure therapy, and eye movement desensitization and reprocessing (EMDR).

Psychogenic blackouts can be caused by a variety of factors, including:

• Threatening feelings, thoughts, or memories
• Stress
• Complicated grief
• Relationship trauma
• Sexual abuse
• Physical, emotional, or psychological trauma in childhood
• Coexisting psychiatric disorders, such as depression, anxiety, personality disorders, or post-traumatic stress disorder (PTSD)

It is important to note that psychogenic blackouts are not the same as fainting or syncope blackouts, which are typically caused by low blood pressure or a lack of blood flow to the brain. Additionally, blackouts can also be caused by alcohol consumption, epilepsy, or other medical conditions. If you or someone you know is experiencing blackouts, it is important to seek medical advice.

Strokes can be treated with clot-busting drugs, medication to reduce brain swelling, or brain surgery

While the symptoms you've described could be indicative of a stroke, they could also be caused by other factors, such as a hypnic jerk, which is a common and benign physiological phenomenon. If you are experiencing these symptoms, it is important to consult a medical professional for a proper diagnosis.

Now, turning to stroke treatments, there are several options available, including clot-busting drugs, medication to reduce brain swelling, and brain surgery.

Clot-busting Drugs

Clot-busting drugs, also known as thrombolysis treatment, are often used to treat ischemic strokes, which are caused by blocked arteries in the brain. One such drug is tissue plasminogen activator (tPA), which works to dissolve blood clots and improve blood flow to the affected area of the brain. A newer medication, tenecteplase, has shown promising results in clinical trials, reducing serious bleeding complications by half compared to the current standard medication, alteplase.

Medication to Reduce Brain Swelling

Cerebral edema, or brain swelling, can be a life-threatening condition that requires immediate treatment. It is often caused by head trauma, stroke, cancer, or other diseases. Medications such as mannitol and other diuretics are used to reduce fluid buildup and swelling in the brain. Corticosteroids are another option, but they can have side effects such as increased appetite, weight gain, and lower resistance to infection.

Brain Surgery

In some cases, surgery may be recommended to treat the underlying cause of a stroke or to prevent another stroke from occurring. One such surgery is a carotid endarterectomy, where a vascular surgeon makes a small cut in the neck to open up a blocked carotid artery and remove plaque buildup. Carotid angioplasty is another procedure where a catheter is inserted into an artery in the leg or arm and guided to the blocked carotid artery. A tiny balloon is then inflated to widen the artery, and a stent is usually left behind to keep it open.

Other surgical procedures can be used to treat ischemic strokes, such as intra-arterial thrombolysis, where medicine is sent directly to the blood clot to dissolve it, or mechanical thrombectomy, where a special wire cage is used to grab and remove the clot.

In conclusion, strokes can be treated with a combination of clot-busting drugs, medication to reduce brain swelling, and surgical procedures. It is important to seek medical attention immediately if you are experiencing any symptoms of a stroke to improve your chances of a full recovery.
