Advanced Neurology LBD prevalence and incidence in India

Appendix

Appendix 1. Search strategy
We primarily aimed to determine the most appropriate search terms that would help obtain pertinent and reliable information.
Thus, HPK did extensive background reading and identified a set of search terms. These were then refined with the help of the
medical research librarian and supervisor. The search was conducted on June 22, 2023, using the final search terms.
1. Incidence* OR Prevalence* OR Epidemiology* OR Diagnosis rate*
2. Lewy body Dementia or dementia with Lewy bodies or Parkinson’s disease dementia or Lewy body disease or dementia
subtypes or dementia* or Alzheimer disease or vascular dementia or frontotemporal dementia OR frontal lobe
dementia OR Korsakoff psychosis OR alcohol related Brain injury OR alcohol-related dementia OR Mixed dementia
3. India*
4. Andhra Pradesh OR Arunachal Pradesh OR Assam OR Bihar OR Chhattisgarh OR Goa OR Gujarat OR Haryana
OR Himachal Pradesh OR Jharkhand OR Karnataka OR Kerala OR Madhya Pradesh OR Maharashtra OR Manipur
OR Meghalaya OR Mizoram OR Nagaland OR Odisha OR Punjab OR Rajasthan OR Sikkim OR Tamil Nadu OR
Telangana OR Tripura OR Uttar Pradesh OR Uttarakhand OR West Bengal OR Ladakh OR Jammu & Kashmir
OR Puducherry OR Lakshadweep OR Delhi OR Chandigarh OR Dadra and Nagar Haveli and Daman & Diu OR
Andaman and Nicobar Islands
5. Amaravati OR Itanagar OR Patna OR Raipur OR Panaji OR Gandhinagar OR Chandigarh OR Shimla OR Ranchi
OR Bengaluru OR Thiruvananthapuram OR Bhopal OR Mumbai OR Imphal OR Shillong OR Aizawl OR Kohima OR
Bhubaneswar OR Chandigarh OR Jaipur OR Gangtok OR Chennai Hyderabad OR Agartala OR Dehradun OR Bhararisain

6. 3 OR 4 OR 5
7. 1 AND 2 AND 6
8. Limit 7 to human
9. Limit 8 to English Language
10. Limit 9 to yr=”1996 -Current”
We thoroughly researched all states, union territories, and corresponding capitals to ensure comprehensive and accurate
data. The names of many states and cities were historically anglicized to reflect the UK’s colonial history in India (e.g., Madras,
Bombay, Orissa, Pondicherry, and Bangalore). Since the turn of the millennium, the use of Indian names has become more
common (e.g., Chennai, Mumbai, Odisha, Puducherry, and Bengaluru, respectively) when referring to these locations. To ensure
that studies were not omitted based on naming conventions, both Indian and anglicized names were included in the search.
The Lewy body dementia (LBD) data are provided in other dementia studies. LBD was also discussed in other dementia
subtype studies. Therefore, several other dementia subtypes, such as Parkinson’s disease, Lewy body disease, dementia
subtypes, Alzheimer’s disease, vascular dementia, frontotemporal dementia, frontal lobe dementia, Korsakoff psychosis,
alcohol-related brain injury, alcohol-related dementia, and mixed dementia, were also incorporated into the search terms to
ensure no missing data on DLB and PDD.
