Understanding Brain Health Conditions

Stroke

A stroke occurs when blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die. Stroke is the second leading cause of death globally and a leading cause of long-term disability.

Recognize the Warning SignsF.A.S.T. — Act Fast to Save a Life

  • Face drooping on one side
  • Arm weakness or numbness in one arm
  • Speech difficulty — slurred or strange speech
  • Time to call emergency services immediately

Why It Matters for African & Underserved Communities

  • Stroke rates in Africa are rising rapidly due to aging populations and increasing rates of hypertension, diabetes, and obesity
  • Most African countries lack acute stroke care infrastructure — no dedicated "stroke units," limited access to CT/MRI scans, and very few hospitals offering clot-busting medication (tPA)
  • The "golden hour" — the critical 4.5-hour window for treatment — is missed in most cases due to delayed care-seeking, transportation barriers, and low awareness
  • Sub-Saharan Africa has approximately 1 neurologist per 4 million people, compared to 1 per 60,000 in the United States
  • Most stroke survivors in low-resource settings receive no formal rehabilitation, leaving lifelong disability untreated

Moyamoya Disease

Moyamoya is a rare cerebrovascular disease in which arteries at the base of the brain become narrowed and blocked. To compensate, the brain forms a network of small, abnormal blood vessels that appear like "puffs of smoke" — moyamoya in Japanese — on brain imaging. It can cause strokes, transient ischemic attacks (TIAs), and progressive neurological damage in young adults and children.

This condition is personal to ANNI. Our founder Christina was diagnosed with Moyamoya, and her lived experience is the foundation of our mission to advance brain health equity.

Recognize the Warning SignsSymptoms of Moyamoya

  • Recurring transient ischemic attacks ("mini-strokes")
  • Strokes — especially unusual in young adults or children
  • Recurring severe headaches
  • Seizures
  • Cognitive decline or learning difficulties (in children)
  • Weakness or paralysis on one side of the body
  • Speech or vision difficulties

Why It Matters for African & Underserved Communities

  • Moyamoya is severely underdiagnosed in Africa — true prevalence is unknown because of lack of advanced diagnostic imaging
  • Diagnosis requires advanced cerebral angiography or MRA — rarely available outside major urban hospitals
  • Often misdiagnosed as epilepsy, migraine, psychiatric illness, or "unexplained" strokes in young patients
  • Treatment requires specialized neurosurgical revascularization (bypass surgery) — virtually unavailable across most of Africa
  • Without treatment, patients face recurrent strokes, progressive disability, and early death
  • Young patients — including children — are most affected, making delayed diagnosis especially tragic
  • ANNI's mission includes building awareness and pathways for Moyamoya diagnosis in underserved settings

Epilepsy

Epilepsy is a neurological disorder marked by recurrent, unprovoked seizures caused by abnormal electrical activity in the brain. It affects more than 50 million people worldwide, making it one of the most common serious neurological conditions globally.

Recognize the Warning SignsSymptoms of Seizures

  • Sudden loss of consciousness or awareness
  • Uncontrollable jerking movements of arms and legs
  • Confusion or staring spells
  • Sudden changes in sensory perception (smell, taste, vision)
  • Loss of bladder or bowel control during an episode
  • Brief memory gaps or "spacing out"
  • Repetitive movements (lip smacking, hand rubbing)

Why It Matters for African & Underserved Communities

  • 80% of the world's 50+ million people with epilepsy live in low- and middle-income countries
  • An estimated 75% of people with epilepsy in Africa receive NO treatment, despite effective anti-seizure medications costing as little as $5 per year
  • Massive stigma — epilepsy is often misattributed to witchcraft, demonic possession, or spiritual punishment, especially in rural communities
  • People with epilepsy face exclusion from school, employment, and even marriage
  • Lack of EEG equipment and trained neurologists prevents proper diagnosis
  • Anti-seizure medications are inconsistently available, even when affordable
  • High rate of SUDEP (Sudden Unexpected Death in Epilepsy) due to untreated seizures
  • Children with epilepsy are often denied education due to stigma, perpetuating poverty

Dementia & Alzheimer's Disease

Dementia is a term for a group of conditions causing progressive decline in memory, thinking, reasoning, and the ability to perform everyday activities. Alzheimer's disease is the most common form of dementia, accounting for 60–80% of cases. Dementia is not a normal part of aging — it is a medical condition that warrants diagnosis and care.

Recognize the Warning Signs10 Warning Signs of Alzheimer's & Dementia

  • Memory loss that disrupts daily life
  • Challenges in planning or solving problems
  • Difficulty completing familiar tasks at home, work, or leisure
  • Confusion with time or place
  • Trouble understanding visual images and spatial relationships
  • New problems with words in speaking or writing
  • Misplacing things and inability to retrace steps
  • Decreased or poor judgment
  • Withdrawal from work or social activities
  • Changes in mood, personality, or behavior

Why It Matters for African & Underserved Communities

  • Dementia rates are rising fastest in Africa due to aging populations and increasing life expectancy
  • WHO estimates approximately 2.4 million people in Africa have dementia today, projected to rise to 7.6 million by 2050
  • Only 5–10% of dementia cases in Africa receive a formal diagnosis
  • Symptoms are often dismissed as "normal aging" or wrongly attributed to witchcraft, ancestral curses, or mental illness
  • Massive caregiver burden falls on families, often women, without medical or financial support
  • Almost no dementia-specific care infrastructure exists across most African countries
  • Cultural stigma can lead to neglect, abandonment, or even abuse of affected individuals
  • Lack of public awareness prevents families from seeking diagnosis, support, or medications that could slow progression

Multiple Sclerosis (MS)

Multiple Sclerosis is a chronic autoimmune disease of the central nervous system in which the body's immune system attacks the protective myelin sheath surrounding nerve fibers in the brain and spinal cord. The damage disrupts communication between the brain and the rest of the body, leading to a wide range of physical, cognitive, and emotional symptoms. MS most often begins between ages 20 and 40 and affects women two to three times more than men.

Recognize the Warning SignsCommon Symptoms of MS

  • Vision problems — blurred or double vision, painful eye movement (optic neuritis), sudden vision loss in one eye
  • Numbness, tingling, or weakness in the face, limbs, or one side of the body
  • Severe fatigue not relieved by rest, often worse in heat
  • Balance problems, dizziness, or unsteady walking
  • Muscle stiffness, spasms, or coordination difficulties
  • Bladder or bowel changes — urgency, frequency, or retention
  • Cognitive changes — memory lapses, slowed thinking, difficulty concentrating
  • Electric-shock sensations down the spine when bending the neck forward (Lhermitte's sign)

Why It Matters for African & Underserved Communities

  • MS was long believed to be rare in Africa — recent studies show prevalence is rising and was severely underestimated due to limited diagnostic infrastructure
  • The MSIF Atlas of MS (3rd Edition) reports that 25 African nations have no MS prevalence data at all, leaving millions undiagnosed
  • In Zambia, the average delay from first symptom to diagnosis is 11.4 months — among the longest documented worldwide
  • Sub-Saharan Africa has fewer than 1 neurologist per 1 million people, and MRI access — essential for MS diagnosis — is extremely limited
  • Black patients with MS in the diaspora face more aggressive disease progression, greater disability, and lower access to disease-modifying therapies than white patients
  • Disease-modifying treatments are largely unavailable or unaffordable across most of sub-Saharan Africa
