Executive Brief

Neuroprotection, BDNF & Brain Resilience in Encephalitis:

Scientific Context for KESUM® (Persicaria minor) & PHYSTA®**

1. Clinical Context: Encephalitis & Brain Injury

Nipah virus infection is frequently complicated by acute encephalitis, a condition associated with high mortality & long-term neurological disability.

Neuroimaging findings report:

·       Hyperintense MRI lesions in ~71% of cases

·       Predominant involvement of the temporal lobes & pons

·       Bilateral white-matter abnormalities

Pathophysiology consistent with micro-embolic injury, neuroinflammation & cerebral edema

These changes reflect structural & functional brain injury, not merely transient inflammation, & are strongly associated with impaired cognitive recovery among survivors.

2. Why BDNF Matters in Encephalitis

Brain-Derived Neurotrophic Factor (BDNF) is a central regulator of:

·       Neuronal survival under inflammatory stress

·       Synaptic plasticity & reconnection

·       White-matter integrity

·       Cognitive & psychosocial recovery

Clinical neuroscience literature consistently shows that declining BDNF levels correlate with worse neurological outcomes, including persistent cognitive impairment after encephalitis, stroke & neurodegenerative conditions.

In severe brain inflammation, preserving neurotrophic capacity becomes a critical determinant of recovery.

3. Human Clinical Evidence: Polygonum minus (KESUM® / Biokesum®)

A randomized, double-blind, placebo-controlled human trial evaluated the effects of Polygonum minus extract over 6 months.

Key clinically significant findings:

·       BDNF increased by 2.03% in the Biokesum® group

·       BDNF decreased by 19.19% in the placebo group (p < 0.05)

·       Triglycerides reduced by 19.05% in the Biokesum® group, while increasing in placebo

The significance lies not only in BDNF elevation, but in prevention of BDNF decline, a factor strongly linked to neuronal vulnerability under inflammatory stress.

These findings support the role of KESUM® as a neuroprotective & neuro-resilience -supporting botanical, rather than a disease-curative agent.

4. Relevance to Brain Swelling & Hyperintense Lesions

Hyperintense MRI lesions represent:

·       Axonal stress

·       Microvascular injury

·       Disrupted neural connectivity

BDNF-supported pathways are directly involved in:

·       Neuronal survival signaling

·       Repair of synaptic connections

Functional recovery following inflammatory or ischemic injury

Thus, maintenance of BDNF may influence the brain’s ability to withstand & recover from encephalitic damage, including white-matter injury associated with edema & micro-embolism.

5. Complementary Role of PHYSTA® (Tongkat Ali)

Across 26 published clinical studies (14 conducted by Biotropics), PHYSTA® has demonstrated:

·       Stress & cortisol modulation

·       Energy metabolism support

·       Immune & physiological resilience

In the context of severe infections:

·       Systemic stress & metabolic exhaustion exacerbate neuroinflammation

·       Physiological resilience indirectly supports neurological outcomes

PHYSTA® is therefore best positioned as systemic resilience support, complementary to neurotrophic strategies.

6. Integrated - Scientific.

Encephalitis damages the brain structurally.

BDNF determines recovery capacity.

KESUM® supports neurotrophic resilience.

PHYSTA® supports systemic stress adaptation.

This framework aligns with current neuroscience understanding while remaining ethically, clinically & regulatorily sound.

7. Nipah virus - related encephalitis results in significant inflammatory & microvascular brain injury.

Neurological outcomes depend not only on infection control, but on preservation of intrinsic brain repair mechanisms.

Human clinical evidence supports Polygonum minus (KESUM®) in maintaining & modestly enhancing BDNF, a key factor in brain resilience.

PHYSTA® supports systemic stress response & immune balance.

Both should be positioned as supportive, not therapeutic, interventions for brain & systemic resilience.

Scientific - Statement :

“In severe encephalitic stress, preserving neurotrophic capacity & systemic resilience may influence neurological outcomes beyond infection control alone.”
