Neurological Expertise

Brain Health Center at Samitivej Sukhumvit Hospital has been designated a Center of Excellence (COE) that provides comprehensive care for brain and neurological conditions. The center covers risk screening, diagnosis, treatment and long-term follow-up, supported by specialist teams and medical technologies that enable more precise care.

Many neurological conditions, especially Alzheimer’s disease, often begin without clear symptoms. By the time symptoms appear, a degree of brain degeneration may have already occurred.
The Neurology Center emphasizes proactive screening (early detection), enabling patients to understand their risk and plan their care in advance.

• Screening identifies early or hidden Alzheimer's pathology in approximately 20% of apparently healthy individuals, enabling risk prediction 5–10 years before symptoms appear and early intervention to slow disease progression.
• Brain and vascular abnormalities are detected in nearly 50% of individuals with risk factors.

Caring for neurological conditions requires more than symptom-based evaluation. It requires understanding abnormalities at the cellular level.
We use a combination of advanced diagnostic tests, interpreted by specialists in neurology and genetics, to enable precise and personalized care.

Examples of early-stage risk detection tests include:

• APOE genotype - assesses genetic risk for Alzheimer’s disease
• Oligomerized amyloid-beta (OAβ) - screens for proteins associated with the disease before symptoms appear
• p-Tau (phosphorylated tau) - detects early brain abnormalities.

Beyond treatment—slowing disease,
with personalized care for the long term.

• Preserves brain function for longer
• Enables confidence in daily living
• Reduces long-term impacts on quality of life
