What is a significant barrier to medication adherence in elderly patients?

Cognitive decline is a significant barrier to medication adherence in elderly patients because it can impair their ability to understand medication instructions, remember dosage schedules, and recognize the importance of taking their medications as prescribed. As cognitive function diminishes, elderly patients may have trouble managing complex regimens involving multiple medications, leading to missed doses or incorrect intake. This decline can manifest in various ways, including confusion, forgetfulness, and decreased ability to follow through on health management tasks.

While limited access to healthcare providers, excessive medication costs, and inconsistent pharmacy hours can also impact medication adherence, cognitive decline directly affects the patient's capacity to engage with their treatment plan. Addressing cognitive issues through support systems, reminders, or simplifying medication regimens can help improve adherence in this vulnerable population. This makes cognitive decline a critical area of focus in ensuring elderly patients successfully manage their medications.
