Can electric shock therapy cause dementia in later life?

While there is some evidence that electroconvulsive therapy (ECT) may be associated with an increased risk of developing dementia in later life, the findings are not conclusive. Most studies have found no association between ECT and dementia, or have found only a small increased risk. However, some studies have found a more substantial increased risk, particularly in older adults and those who have received multiple ECT treatments.

It is important to note that ECT is a safe and effective treatment for a variety of mental health conditions, and the risk of dementia is relatively small. The decision of whether or not to undergo ECT should be made in consultation with a psychiatrist, who can assess the risks and benefits of treatment.

Some studies have suggested that ECT may actually improve cognitive function in some people with dementia. However, more research is needed to confirm these findings.

Overall, the evidence on the relationship between ECT and dementia is mixed. More research is needed to determine whether ECT does indeed increase the risk of dementia, and if so, to what extent.
