Brain Haemorrhage: Signs, Diagnosis, Treatment & Prevention Guide.
🧠 What Is a Brain Haemorrhage?
A brain haemorrhage, medically termed intracerebral hemorrhage (ICH), refers to focal bleeding from a blood vessel within the brain parenchyma. This bleeding creates a pool of blood called a hematoma that can compress and damage surrounding brain tissue.
Unlike ischemic strokes caused by blocked blood vessels, haemorrhagic strokes involve bleeding and are considered the most devastating and disabling type of stroke.
Most intracerebral hemorrhages occur in the basal ganglia, cerebral lobes, cerebellum, or pons. The most common location for hemorrhage due to hypertension is the putamen.
📋 Types of Brain Haemorrhage
Brain haemorrhages are classified based on where the bleeding occurs:
| Type | Location | Common Causes |
|---|---|---|
| Intracerebral Hemorrhage | Inside brain tissue | High blood pressure, trauma |
| Subarachnoid Hemorrhage | Between brain and skull layers | Aneurysm rupture |
| Subdural Hematoma | Between dura and brain | Head injury, falls |
| Epidural Hematoma | Between skull and dura | Severe head trauma |
⚠️ Causes and Risk Factors
Primary Causes
High blood pressure (hypertension) is the most common cause of spontaneous brain haemorrhage. Chronic hypertension weakens blood vessel walls, leading to the formation of microaneurysms (Charcot-Bouchard aneurysms) that may rupture.
Other causes include:
- Head injury or trauma (most common in people under 50)
- Aneurysms (bulges in blood vessel walls)
- Arteriovenous malformations (AVMs) — abnormal connections between arteries and veins
- Cerebral amyloid angiopathy — protein buildup in brain arteries (common in older adults)
- Blood clotting disorders
- Excessive anticoagulation (blood thinner use)
- Brain tumours (primary or metastatic)
- Moyamoya disease
- Vasculitis (blood vessel inflammation)
Risk Factors
| Modifiable | Non-Modifiable |
|---|---|
| High blood pressure | Older age |
| Smoking | Previous brain haemorrhage |
| Unhealthy diet | Family history of aneurysms/AVMs |
| Heavy alcohol use | Genetic conditions |
| Cocaine or amphetamine use | — |
| Use of anticoagulants/antiplatelet drugs | — |
| Obesity | — |
🚨 Signs and Symptoms
Emergency Warning Signs
Brain haemorrhage symptoms typically begin suddenly, often during activity.
| Symptom | Description |
|---|---|
| Sudden severe headache | Often described as "the worst headache of my life" |
| Loss of consciousness | Can occur within seconds to minutes |
| Weakness or paralysis | Usually affects one side of the body (hemiparesis) |
| Nausea and vomiting | Very common |
| Seizures | Focal or generalized |
| Difficulty speaking | Slurred speech or inability to speak |
| Vision changes | Impaired or lost vision; eyes pointing in different directions |
| Confusion or delirium | Reduced awareness of surroundings |
| Balance problems | Difficulty walking or standing |
Note: In older adults, headache may be mild or absent.
When a Small Haemorrhage Occurs
Small haemorrhages may cause focal deficits without affecting consciousness, with minimal or no headache and nausea. These cases can mimic ischemic strokes.
Complications
Large haemorrhages can lead to:
- Brain herniation — brain tissue being forced through rigid skull structures
- Hydrocephalus — cerebrospinal fluid accumulation in the brain
- Coma and death
Approximately half of patients with large haemorrhages die within a few days.
🏥 When to See a Doctor
A brain haemorrhage is a medical emergency.
Seek emergency care immediately if you or someone else develops:
- Sudden severe headache
- Sudden weakness or numbness
- Difficulty speaking or understanding speech
- Loss of consciousness
- Seizures
- Sudden vision problems
Even if symptoms seem to improve, especially after a fall, in someone with high blood pressure, or in anyone taking anticoagulant medication, a quick evaluation is essential.
🔬 Diagnosis
Neurological Examination
Diagnosis begins with a neurological examination to assess:
- Alertness and consciousness
- Speech and language function
- Strength and coordination
- Pupil response
- Balance and walking
Imaging Tests
| Test | Purpose | When Used |
|---|---|---|
| Non-contrast CT scan | Detects most brain bleeds rapidly | First-line test in emergencies |
| MRI | Provides more detail about age, location, and cause | Used later or in specific situations |
| CT Angiography (CTA) | Identifies vessel abnormalities | When aneurysm/AVM is suspected |
| MR Angiography (MRA) | Evaluates blood vessels | Alternative to CTA |
Blood Tests
Blood tests are done to:
- Measure blood sugar (low sugar can mimic stroke symptoms)
- Check platelet count
- Determine blood clotting time
- Assess medication effects
💊 Treatment Options
Treatment depends on the location and size of the bleed, the cause, and the patient's stability.
Medical Management
| Treatment | Purpose |
|---|---|
| Blood pressure control | Reduce risk of further bleeding; target systolic < 140 mmHg |
| Reversal of anticoagulation | Stop blood thinners' effects when appropriate |
| Seizure management | Antiepileptic drugs for seizures |
| Intracranial pressure monitoring | For large haemorrhages |
| Ventilation support | Oxygen and airway protection |
| Intravenous fluids | Careful fluid management |
Surgical Treatment
Surgery may be considered when:
- Bleeding causes pressure on the brain
- Hematoma volume > 30 cm³
- Structural problem is identified
- Cerebellar hematoma > 3 cm in diameter
Surgical options include:
- Haematoma evacuation — surgical removal of accumulated blood
- Ventriculostomy — for patients with intraventricular haemorrhage, hydrocephalus, or elevated ICP
- Treating vessel abnormalities — clipping aneurysms, removing AVMs
Stroke Unit Care
Patients are typically managed in intensive care or stroke units for close observation and monitoring of consciousness and neurological function.
🛡️ Prevention and Self-Care
Preventing Brain Haemorrhage
Not every brain haemorrhage can be prevented, but risk can often be lowered.
| Action | Benefit |
|---|---|
| Regular blood pressure monitoring | Keep below 120/80 mmHg |
| Take medications as prescribed | Control hypertension and other conditions |
| Use seat belts and helmets | Prevent head injuries |
| Limit alcohol consumption | Heavy drinking increases risk |
| Quit smoking | Reduces aneurysm formation risk |
| Healthy diet | Low in saturated fats, trans fats, and calories |
| Regular exercise | Maintains healthy weight and blood pressure |
| Manage stress | Chronic stress can raise blood pressure |
After Treatment
Recovery may continue for weeks or months. Important steps include:
- Taking medications consistently
- Attending follow-up appointments
- Keeping a record of blood pressure readings
- Following activity restrictions
- Starting rehabilitation early (physical, occupational, speech therapy)
❓ Frequently Asked Questions
Q1: What is the survival rate for brain haemorrhage?
Approximately 50% of patients with large intracerebral haemorrhages die within the first few days. Survival depends on the size of the haemorrhage, the patient's age, and how quickly treatment begins.
Q2: Can stress cause a brain haemorrhage?
Chronic stress alone does not directly cause a brain haemorrhage, but it can contribute to high blood pressure, which significantly increases the risk.
Q3: Can a brain haemorrhage happen during sleep?
Yes, a brain haemorrhage can occur at any time, including during sleep.
Q4: Is brain haemorrhage hereditary?
Some conditions that increase the risk, like aneurysms or AVMs, can be hereditary. However, lifestyle factors play a major role in most cases.
Q5: Can brain haemorrhage be treated completely?
Survivors often experience gradual improvement as the blood is absorbed. Some patients have surprisingly few neurological deficits because haemorrhage can be less destructive to brain tissue than infarction. However, many survivors have permanent deficits that require rehabilitation.
Q6: What is the difference between brain haemorrhage and stroke?
A brain haemorrhage is one type of stroke (haemorrhagic stroke). It involves bleeding within the brain, while the more common type of stroke (ischemic) involves blocked blood vessels.
Q7: Should I stop my blood thinner after a brain haemorrhage?
Never stop blood-thinning medication without consulting your doctor. Treatment may involve temporary reversal of anticoagulation under medical supervision, but decisions are made on a case-by-case basis.
