Posterior Pure Sensory Stroke (PPSS) is a rare type of stroke that affects the sensory areas of the brain. Unlike other types of strokes, PPSS primarily impairs the sense of touch, temperature, and body position without causing motor or speech problems. In this article, we’ll explore PPSS in simple, plain English to help you understand its types, causes, symptoms, diagnosis, treatments, medications, and potential surgical options.
Types of Posterior Pure Sensory Stroke:
PPSS can be categorized into two main types based on its underlying causes:
- Embolic PPSS:
- Description: Embolic PPSS occurs when a blood clot or debris from another part of the body travels to the brain and blocks a blood vessel.
- Causes: Heart conditions, such as atrial fibrillation, can lead to the formation of blood clots that may travel to the brain and cause embolic PPSS.
- Lacunar PPSS:
- Description: Lacunar PPSS is usually caused by small blood vessel disease in the brain, leading to the formation of small, localized strokes.
- Causes: Hypertension (high blood pressure) is a common risk factor for lacunar PPSS, as it can damage small blood vessels in the brain over time.
Common Causes of Posterior Pure Sensory Stroke
- High blood pressure (hypertension)
- Atrial fibrillation (irregular heartbeat)
- Diabetes
- Smoking
- High cholesterol levels
- Obesity
- Excessive alcohol consumption

- Traumatic brain injury
Common Symptoms of Posterior Pure Sensory Stroke
- Numbness or tingling in one side of the body
- Loss of sensation in the face, arms, or legs

- Altered sense of body position
- Problems with coordination and balance
- Difficulty feeling textures or objects
- Inability to localize touch
- Impaired fine motor skills

- Slurred speech (rare)
- Confusion or memory problems (rare)
- Mood swings or emotional changes (rare)
- Difficulty swallowing (rare)
- Loss of consciousness (rare)
- Difficulty breathing (rare)
- Seizures (rare)
- Paralysis (rare)
Diagnostic Tests for Posterior Pure Sensory Stroke
- Magnetic Resonance Imaging (MRI) – to visualize the brain and identify the location of the stroke.
- Computed Tomography (CT) Scan – may be used to rule out bleeding in the brain.
- Electrocardiogram (ECG or EKG) – to check for irregular heart rhythms.
- Holter Monitor – records the heart’s electrical activity over time to detect heart rhythm abnormalities.
- Echocardiogram – to examine the structure and function of the heart.
- Carotid Ultrasound – to assess blood flow in the carotid arteries.
- Blood Pressure Monitoring – to check for hypertension.
- Blood Tests – to measure cholesterol levels, blood sugar, and blood clotting factors.
- Lumbar Puncture (Spinal Tap) – may be performed in some cases to rule out other conditions.
- Electroencephalogram (EEG) – to detect abnormal brain activity.
- Somatosensory Evoked Potentials (SSEP) – measures the speed of sensory nerve signals.
- Doppler Ultrasound – to assess blood flow in major arteries.
- Transcranial Doppler (TCD) – evaluates blood flow in the brain.
- Angiography – uses contrast dye to visualize blood vessels in the brain.
- Blood Coagulation Tests – to check for clotting disorders.
- Urinalysis – to assess kidney function.
- Chest X-ray – to evaluate lung health.
- Complete Blood Count (CBC) – checks for signs of infection or anemia.
- Serum Creatinine Test – to assess kidney function.
- Genetic Testing – may be recommended in some cases to identify inherited conditions.
Treatment Options for Posterior Pure Sensory Stroke
- Medications to prevent blood clots:
- Anticoagulants (e.g., warfarin or novel oral anticoagulants) to reduce the risk of clot formation.
- Antiplatelet drugs (e.g., aspirin or clopidogrel) to prevent platelets from sticking together.
- Blood pressure management:
- Medications like ACE inhibitors or calcium channel blockers may be prescribed to control high blood pressure.
- Diabetes management:
- Insulin or oral medications may be necessary to control blood sugar levels.
- Lifestyle modifications:
- Quitting smoking and reducing alcohol intake can reduce stroke risk.
- Adopting a healthy diet and regular exercise routine can improve overall health.
- Physical therapy:
- A physical therapist can help patients regain strength, coordination, and balance.
- Occupational therapy:
- Occupational therapists assist patients in relearning daily tasks and fine motor skills.
- Speech therapy (if needed):
- Speech therapists work with patients experiencing speech or swallowing difficulties.
- Medications for specific symptoms:
- Medications to manage vertigo, headaches, or nausea may be prescribed as needed.
- Prevention of future strokes:
- Healthcare providers may recommend long-term medications and lifestyle changes to prevent recurrent strokes.
- Supportive care:
- Emotional and psychological support from counselors or support groups can be beneficial.
- Assistive devices:
- Depending on the severity of symptoms, assistive devices like canes or braces may be required.
- Rehabilitation programs:
- Inpatient or outpatient rehabilitation programs may be recommended for comprehensive care.
- Monitoring and follow-up:
- Regular check-ups with healthcare providers to monitor progress and adjust treatment as needed.
- Dietary changes:
- A diet low in salt and saturated fats can help manage blood pressure and cholesterol levels.
- Weight management:
- Achieving and maintaining a healthy weight reduces stroke risk.
- Alcohol moderation:
- Limiting alcohol consumption to recommended levels is essential.
- Stress management:
- Stress-reduction techniques, such as meditation or yoga, can be helpful.
- Treatment of underlying conditions:
- Addressing conditions like sleep apnea, heart disease, or clotting disorders may be necessary.
- Avoiding illicit drugs:
- Staying away from drugs like cocaine or amphetamines is crucial for stroke prevention.
- Fall prevention strategies:
- Installing handrails, removing tripping hazards, and using mobility aids can prevent falls.
