A person in Clinton, MD spends years being treated for depression, but the low moods never fully lift. Eventually, an evaluation points to previously undiagnosed ADHD, which may explain some of the frustration and self-doubt that had built up over the years. Overlapping conditions are common, and they are easy to miss when care focuses on one label. That is where an OCD and ADHD treatment, Anxiety and depression specialist can help, by looking at the full pattern instead of one diagnosis.

Mental Health Conditions Often Come in Pairs

It is common for two or more conditions to occur in the same person. When they do, symptoms blur, and treating one while missing another can leave important symptoms unresolved.

  • About 70 percent of adults with ADHD have at least one other mental health condition, such as anxiety, depression, bipolar disorder, or a substance use disorder, a 2025 review reported.
  • Up to half also have an anxiety disorder, and estimates of co-occurring depression range from roughly 19 to 53 percent, according to the same 2025 review.
  • OCD frequently occurs alongside anxiety and depression, and its symptoms can overlap with those conditions.

One Condition Often Masks Another

Overlapping conditions are easy to miss. The most obvious problem draws attention, while a quieter one goes unnamed. A teenager treated for anxiety may also have ADHD that no one has screened for. An adult managing depression may have lived with OCD for years without calling it that. When an evaluation focuses on the most obvious symptoms, another condition can go unrecognized. A thorough first evaluation can help identify conditions that might otherwise be missed.

Sorting Out the Pattern Takes a Full Evaluation

Untangling overlapping conditions takes time and a thorough evaluation. A provider looks at when each symptom started, how they interact, and which one causes the most trouble day to day. Rating scales, personal history, and sometimes input from family help separate, for example, the restlessness of ADHD from the restlessness of anxiety.

Nearly 8 in 10 children with ADHD have at least one other condition, and about 4 in 10 have anxiety, according to CDC data. ADHD often starts in childhood and can continue into adulthood, making early recognition important when symptoms persist.

Why One Diagnosis at a Time Falls Short

When conditions overlap, treatment can get tricky. Medication choices need more care when ADHD occurs alongside anxiety, depression, or another condition. An antidepressant also needs careful consideration when bipolar disorder has not been identified, since treatment for the two conditions differs. The provider needs to know what else is going on before choosing medication.

Coordinated Care Handles the Full Picture

Overlapping conditions are manageable with the right approach. One provider or team overseeing the different conditions can keep medication choices and treatment decisions connected.

For someone with several conditions, care in Maryland often means different providers, separate appointments, and treatment plans that do not line up. In Clinton, MD, and across Prince George’s County, finding several behavioral health specialists can mean managing separate appointments and longer waits. A practice that treats several of these conditions can handle more of the care through one provider or team. At Altitude Behavioral Care and Integrative Health, providers evaluate and treat ADHD, anxiety, depression, OCD, and bipolar disorder in one place, with care available across Maryland in person and by video.

If treatment for one condition has never fully worked, a second, unrecognized condition may be part of the reason. A full evaluation can help identify whether another condition is affecting symptoms and what treatment options may fit.
