Diabetes and ADHD: In-Depth Relationship, Causes, and Treatment Dynamics

Harold Robert Meyer | The ADD Resource Center 08/01/2025

Overview

Diabetes (Type 1 and Type 2) and Attention Deficit Hyperactivity Disorder (ADHD) are both common lifelong conditions. Recent research reveals significant associations between the two, with overlapping challenges around disease management, shared risk factors, and unique clinical implications for individuals, families, and healthcare teams.

Relationship Between Diabetes and ADHD

Prevalence & Bidirectional Links

• People with ADHD are at higher risk of diabetes:
  • There is a 37% increased prevalence of Type 1 diabetes (T1D) and a more than doubled risk of Type 2 diabetes (T2D) in people with ADHD compared to those without ADHD123.
• Diabetes patients have increased rates of ADHD:
  • Around 35% of individuals with T1D also meet criteria for ADHD, a rate notably higher than in the general population14.
• This relationship is bidirectional; having one condition raises the risk for the other 15.

Clinical Interactions

• Worse glycemic control and higher complication rates have been reported in patients with both diagnoses, including higher HbA1c levels, more frequent hypoglycemic episodes, diabetic ketoacidosis (DKA), and diabetes-related hospitalizations16789.
• Children and adults with both disorders require more frequent and complex healthcare interventions68.

Reasons for the Relationship

Biological & Environmental Factors

• Neurological and metabolic mechanisms: Diabetes, especially T1D, may impact brain regions involved in attention and executive function due to swings in blood glucose, contributing to ADHD symptoms and cognitive dysfunction14.
• Shared genetic and inflammatory pathways: Some gene variants affect both neurodevelopment and metabolic regulation; inflammatory and endocrine disruptions involved in diabetes may influence neural development110.
• Perinatal and maternal health: Children born to mothers with diabetes during pregnancy have increased risk of developing ADHD, with greatest risk seen with maternal T1D5.

Behavioral and Lifestyle Overlap

• Eating and self-care patterns: ADHD impulsivity and reward-seeking make individuals prone to erratic eating, preference for high-sugar foods, and difficulty with structured routines—all risk factors for obesity and T2D311.
• Mental health comorbidities: Anxiety, depression, and emotional regulation issues common in both conditions may contribute to unhealthy behaviors, medication nonadherence, and higher complication rates16.

Treatment Considerations for Comorbid Diabetes and ADHD

Challenges in Disease Management

• Adherence barriers:
  • ADHD symptoms—especially inattention, forgetfulness, impulsivity, and poor executive function—can undermine complex diabetes care routines, such as regular blood glucose checks, insulin dosing, medication adherence, and tracking carbohydrate intake3712.
  • Forgetting or delaying medication and meals may increase risk for hypoglycemia and other complications7.
• Health outcomes: Poor self-management in the context of ADHD increases the risk of acute and chronic diabetes-related health problems, higher healthcare utilization, and suboptimal glycemic control689.

Integrated Treatment Strategies

Area	Recommendations
Diagnosis	Routine screening for ADHD in people with diabetes (especially if glycemic control is poor or adherence is low); screening for diabetes risk in people with ADHD14.
Care coordination	Multidisciplinary approach—collaboration between endocrinologists, primary care, mental health professionals, and diabetes educators; clear communication and shared goals112.
ADHD management	Pharmacological therapies (e.g., stimulants, non-stimulants) and behavioral interventions; evidence suggests that treating ADHD may improve diabetes management and reduce hospitalizations67.
Diabetes management	Simplified and structured regimens, electronic reminders, visual aids, use of health apps, and caregiver support12. Adjust treatment plans to minimize cognitive and adherence demands.
Education & Support	In-depth patient and family education on the importance of daily routines, help with establishing reminders, and ongoing psychosocial support412.
Monitoring	More frequent follow-up visits, closer glucose and behavioral monitoring, and assessment of treatment efficacy for both conditions16.

Additional Notes

• Early intervention for ADHD and tight glycemic control in youth with diabetes can help reduce long-term educational and health complications4.
• Individualized, empathetic care planning, adapted to each patient’s cognitive and behavioral strengths and challenges, is crucial for successful outcomes.

Conclusion

The interplay between diabetes and ADHD is complex, rooted in both biological and behavioral factors. Comorbidity presents a higher risk for complications and requires a highly coordinated, tailored approach to care. Awareness of the association, proactive screening, patient-centered interventions, and regular follow-up by different healthcare providers are critical for optimizing outcomes for those living with both conditions164.
