| Thailand's aging trend is creating a long-term care gap. | Most elderly Thais age at home and are looked after by families; World Bank projects Thais over 80 needing assistance will increase more than six-fold to almost 2.5 million over two decades. | Thailand | Older adults and families | [World Bank: Caring for Thailand's Aging Population](https://www.worldbank.org/en/country/thailand/publication/caring-for-thailand-s-aging-population) | Official report page | 2021 | Supports family-caregiver burden and long-term care pressure | High |
| Institutional long-term care is not broadly covered. | Thailand's Universal Coverage Scheme does not currently cover institutional long-term care, and programs helping families with these expenses are limited. | Thailand | Older adults with high needs, including dementia | [World Bank: Caring for Thailand's Aging Population](https://www.worldbank.org/en/country/thailand/publication/caring-for-thailand-s-aging-population) | Official report page | 2021 | Supports product focus on home/family caregiving rather than institution-only care | High |
| Thailand's dementia population is expected to grow sharply. | A BMJ Open paper cites estimates of about 600,000 elderly people with dementia in Thailand in 2015, potentially exceeding 1 million by 2030 and 2 million by 2050. | Thailand | Older adults with dementia | [BMJ Open: Health and long-term care of the elderly with dementia in rural Thailand](https://bmjopen.bmj.com/content/10/3/e032637) | Peer-reviewed paper | 2020 | Core problem-size evidence for dementia-specific focus | Medium-high |

| Rural Thai dementia care relies heavily on informal caregivers. | In a rural Thailand sample, 86% of dementia caregivers were household informal caregivers; half also worked outside the home; half had no support and no minor caregivers. | Thailand | 140 caregivers of people with dementia | [BMJ Open: Health and long-term care of the elderly with dementia in rural Thailand](https://bmjopen.bmj.com/content/10/3/e032637) | Peer-reviewed paper | 2020 | Direct evidence that caregiver wellness is exposed | High |

| Thai dementia caregivers report concrete support needs. | In a survey of 88 Thai dementia caregivers, top needs were caregiver education/training, a telephone consultation line, and rapid hospital access for dementia patients. | Thailand | Thai dementia caregivers | [JMAT / ThaiScience: Caregiver Burden and Needs of Dementia Caregivers in Thailand](https://www.thaiscience.info/journals/Article/JMAT/10746030.pdf) | Peer-reviewed paper PDF | Unknown | Maps directly to AI education, triage, and handoff workflows | High |
| Dementia patient dependency predicts caregiver burden. | The same Thai caregiver-burden study found dependency in basic ADLs correlated with higher caregiver burden (OR 7.48, 95% CI 1.42-39.53, p=0.02). | Thailand | Thai dementia caregivers | [JMAT / ThaiScience](https://www.thaiscience.info/journals/Article/JMAT/10746030.pdf) | Peer-reviewed paper PDF | Unknown | Supports tracking functional dependency and burden signals | High |

| Thai caregivers often receive little formal preparation. | The 2025 study reports that all dementia patients in its sample had one caregiver and none of the family caregivers had received training in caring for older people. | Thailand | Family caregivers | [PMC: Exploring dementia care for community-dwelling older adults in Thailand](https://pmc.ncbi.nlm.nih.gov/articles/PMC12319683/) | Peer-reviewed paper | 2025 | Supports lightweight Thai-first coaching | Medium-high |

## Synthesis

The evidence supports the core thesis: Thailand's aging trend is increasing dementia-care demand while family-based home care remains central. Formal long-term care is expensive, limited, and not fully covered. Dementia care is not a short one-time need; it produces ongoing uncertainty, practical burden, financial pressure, and emotional strain inside the family.

The strongest Thailand-specific evidence comes from three sources:

1. World Bank's aging and long-term care report.
2. BMJ Open's rural Thailand dementia-care study.
3. JMAT/ThaiScience's Thai dementia caregiver burden study.

The strongest global evidence comes from WHO and ADI:

1. WHO shows dementia is rising globally and carer support is a formal public-health action area.
2. ADI shows dementia stigma and misunderstanding are still widespread, which supports education and culturally localized guidance.

## Product Implications

- Build for the family caregiver first, not the patient first.
- Use Thai-first education, incident logging, family handoff, burden check-ins, and escalation guidance.
- Treat caregiver stress as a product signal, not just a side note.
- Do not claim diagnosis, treatment, medication decisions, or emergency decision-making.
- The MVP should show how AI turns a stressful voice story into structured support and a family handoff summary.

## Decision

Proceed to product definition. The problem is real enough for a hackathon MVP, but the product should narrow to "caregiver wellness and family coordination for dementia care at home" rather than broad eldercare or clinical dementia management.
