Definition

Binswanger disease also known as subcortical arteriosclerotic degeneration of the white matter encephalopathy is a progressive neurological , uncontrolled, arterial disorder caused by arteriosclerosis and thromboembolism affecting the blood vessels that supply the white matter and deep structures of the brain (basal and thalamus). Most patients experience progressive loss of memory and intellectual abilities (), or , and an abnormally slow, shuffling, the unsteady pattern of walking, usually over a 5-10 year period. The explanation most often proposed is that chronic arterial hypertension is responsible for the narrowing of the small blood vessels due to lipohyalinosis and with subsequent blood flow reduction and . Due to their vascular etiology, the symptoms and physical findings associated with Binswanger disease may suddenly worsen due to , stabilize and then improve for a brief time, but the patient’s overall condition continues to progress as the blood vessels become increasingly obstructed. Binswanger’s disease represents one of the causes which lead to vascular cognitive impairment alongside cerebral lacunes, amyloid angiopathy, and some forms of Alzheimer’s disease, and it may coexist with any of these disorders.

Symptoms

Affected individuals often become depressed, uncaring (apathetic), inactive, and unable to act or make decisions (abulic). They become withdrawn and exhibit poor judgment, reduced planning and organizational skills, and less spontaneous communication. In addition, affected individuals may have difficulty with speech (dysarthria), swallowing (), and control (incontinence). Some patients exhibit abnormalities that are similar to those seen in Parkinson’s disease, such as slowness, poor balance, and short, shuffling steps (Parkinsonism). is usually not a feature.

Cognitive and behavioral impairment, motor and gait disturbances, falls, and incontinence evolves with periods of stabilization, plateaus, and periods of improvement. A mixture of pyramidal tract signs, extrapyramidal signs, and pseudobulbar signs can often be seen

Many individuals with Binswanger disease have a history of strokes or transient ischemic attacks. Consequently, the symptoms and signs of this disease develop in a stuttering or stepwise fashion; in contrast to the insidious, gradually progressive course of neurodegenerative diseases.

Causes

Binswanger disease is caused by arteriosclerosis, thromboembolism, and other diseases that obstruct blood vessels that supply the deep structures of the brain. Hypertension, smoking, hypercholesterolemia, heart disease, and are risk factors for Binswanger disease. Cognitive and behavioral changes are characterized by dementia and a dysexecutive (changes in attentional control, working memory, and short‐term memory, impulse control, and abulia in the final stages). Rare diseases such as CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) also cause Binswanger disease. Thus, Binswanger disease is a syndrome of vascular dementia with multiple causes, not a specific disease. The reduced blood flow in brain tissue appears to produce secondary that may be a target for treatment.

The diagnosis of Binswanger disease is usually based on a thorough clinical evaluation, including detailed patient history, physical examination, and () or computerized tomography () scanning of the brain. MRI and CT reveal nerve fiber (white matter) degeneration and multiple small strokes in the deep structures of the brain.

The neurological examination showed the following:

  1. Pyramidal tract signs are characterized by hemiparesis regarding the right limbs with a score of 4/5 (on the MRC—Modified Research Council scale). Extensor plantar reflex was objectified in the right leg. The patient also had central face palsy on the same side.
  2. Extrapyramidal signs are characterized by slowness, left upper limb rigidity, hypomimia, and a low‐volume, monotonous speech.
  3. Mild cognitive impairment on MMSE testing (a score of 27/30) and on MOCA testing (25/30). The abilities affected in our patient were visuospatial/executive functions, short‐term memory, and mathematical functions.

Treatment

The ischemic brain damage in Binswanger disease is not reversible, so treatment is focused on reducing risk factors for stroke, thereby retarding the of the disease. Treatment usually involves the use of anti-hypertensive drugs to control blood pressure, antiplatelet drugs (e.g., aspirin) or warfarin to reduce thromboembolism, statins to reduce atherosclerosis, smoking cessation, and diabetes control. Antidepressant drugs are helpful in the management of depression associated with Binswanger disease. Another treatment is symptomatic and supportive.

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Rest, drink safe water, and observe symptoms carefully.
  • Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
  • Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

  • For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
  • Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
  • Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Severe symptoms, confusion, fainting, breathing difficulty, chest pain, severe dehydration, or sudden weakness need urgent medical care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Binswanger Disease

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
