Frequency of Idiopathic Normal Pressure Hydrocephalus

Burden of hydrocephalus disease in Colombia (2015-2024): An AVAD/DALYS analysis from official sources

“…This percentage is slightly higher in the male population and coincides with other international studies where a higher burden is also observed in males, possibly associated with biological factors and even greater underreporting in females [18], which shows a differential distribution by sex in the burden of disease and highlights the prolonged impact of hydrocephalus on patients' quality of life. Likewise, they indicate that most of the burden is due to morbidity and not mortality.…”

“…However, in older adults, the burden increases again, with peaks in the 60-69, 70-79, and over 80 age groups, suggesting the influence of etiological factors associated with both congenital and acquired conditions. According to Casmiro et al [18], normotensive hydrocephalus or secondary cases are characteristic of aging and neurodegenerative diseases.…”

Prevalence of idiopathic normal pressure hydrocephalus in older adult population in Shanghai, China: A population‐based observational study

“…Additionally, despite several studies conducted on community populations that were well-represented and showed varying prevalence rates of iNPH ranging from 0.51% to 3.7% among those over 65 years old, 10,15,17,32,33 with rates as high as 5.9%-8.9% among those over 80 years old, 10,33,34 (90-99) and centenarian cohorts (100-103), the prevalence soared to 8.36% and 9.09%, respectively. These remarkable discoveries have delicately filled a crucial gap in our understanding of the prevalence of this disease among the elderly.…”

“…This might have led to either an overestimation or underestimation of the prevalence due to the lack of representativeness of the target population. Additionally, despite several studies conducted on community populations that were well‐represented and showed varying prevalence rates of iNPH ranging from 0.51% to 3.7% among those over 65 years old, 10,15,17,32,33 with rates as high as 5.9%–8.9% among those over 80 years old, 10,33,34 a common issue that persisted was the low response rate among surveyed participants. For instance, one study 17 in the Tajiri region of Japan reported a 75% response rate, while another Japanese study 20 had a response rate of 69.2%.…”

Prevalence of possible idiopathic normal pressure hydrocephalus in older inpatients with schizophrenia: a replication study

“…The risk of type 2 DM is 2-to 5-fold higher in SZ patients compared to general population [23]. In addition, it has been reported that metabolic syndrome itself (DM, hypertension, and hyperlipidemia) are also risk factors for iNPH [24][25][26]. We have hypothesized that these reasons increase the prevalence of iNPH in SZ population compared with the general population, and that is also higher the previously estimated prevalence in SZ population (3.1%).…”
