Summary
Cognitive function, specifically executive control function (ECF), is linked to medication adherence in older Hispanic adults with type 2 diabetes. Poorer ECF performance correlates with lower adherence and worse glycemic control.
Area of Science:
- Gerontology
- Neuroscience
- Endocrinology
Background:
- Medication nonadherence is a significant challenge in managing type 2 diabetes, particularly among older adults.
- Cognitive function, including executive control function (ECF), may influence medication adherence in this population.
Purpose of the Study:
- To investigate potential cognitive and demographic correlates of medication nonadherence in older Hispanic adults with type 2 diabetes.
- To determine if ECF performance correlates with medication adherence or glycemic control in this demographic.
Main Methods:
- Forty community-dwelling Hispanic adults aged 65+ with type 2 diabetes participated.
- Executive control function (ECF) was assessed using the executive clock drawing task (CLOX 1) and the Executive Interview.
- Self-reported medication adherence (visual analog scale) and glycemic control (HbA1c) were measured.
Main Results:
- Lower adherence scores correlated with poorer CLOX 1 performance and worse HbA1c.
- ECF performance (CLOX 1) and educational level were significantly associated with medication adherence.
- A CLOX 1 cutoff score of 7 was highly sensitive for predicting <90% adherence.
Conclusions:
- A relationship exists between executive control function (ECF), as measured by the CLOX 1 instrument, and self-reported medication adherence in older Hispanic adults with type 2 diabetes.
- Cognitive assessment, particularly of ECF, may aid in identifying individuals at risk for nonadherence.

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Nucleophilic substitution reactions of alkyl halides can proceed via an SN1 or an SN2 mechanism. While in SN2 reactions, the nucleophile attacks the substrate simultaneously as the leaving group departs, in SN1 reactions, the substrate first dissociates to give the carbocation intermediate. Various factors such as the structure of the substrate, the strength of the nucleophile, and the nature of the solvent promote one mechanism over the other.

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...
