Should sitting heads of state be required to undergo comprehensive cognitive and health evaluations made public?

Context

The question of whether sitting heads of state should undergo mandatory public cognitive and health evaluations touches on tensions between transparency, medical privacy, and democratic accountability. Proponents argue that voters deserve assurance about a leader's fitness to govern, particularly given the cognitive demands of high office; critics contend that such requirements could set dangerous precedents for medical discrimination and infringe on personal privacy rights. The debate has intensified in recent years as aging populations in developed democracies have raised questions about cognitive decline in office.
