Which condition is NOT allowed to be excluded from coverage in long-term care policies sold in Connecticut?

In Connecticut, long-term care policies are designed to provide coverage for a variety of conditions, and there are specific regulations in place regarding what can and cannot be excluded from coverage. Senile dementia, which includes conditions such as Alzheimer's Disease, is a category that must be covered in long-term care insurance policies. This is because these conditions typically affect an individual's cognitive function and necessitate long-term care, which is the primary purpose of these insurance policies.

Alzheimer's Disease and Parkinson's Disease are explicitly noted as significant health issues that often lead to a need for long-term care, thus making exclusions for these conditions not permissible under Connecticut law. Multiple Sclerosis, while a serious condition, also falls under the categories that require coverage.

Therefore, the correct answer highlights that senile dementia should be included in coverage rather than excluded, aligning with the regulatory framework established to protect consumers seeking long-term care insurance.
