Summary
Certain temperamental traits, specifically cyclothymic and irritable, may predict adult attention deficit-hyperactivity disorder (ADHD) independently of bipolar disorder (BD). These findings highlight potential biomarkers for adult ADHD persistence.
Area of Science:
- Psychiatry
- Neuroscience
- Clinical Psychology
Background:
- Attention deficit-hyperactivity disorder (ADHD) can persist into adulthood, impacting individuals significantly.
- Understanding the factors contributing to adult ADHD persistence, independent of other conditions like bipolar disorder (BD), is crucial for effective diagnosis and treatment.
- Temperamental traits represent stable personality characteristics that may influence the course of psychiatric disorders.
Purpose of the Study:
- To investigate the association between specific temperamental traits and the persistence of ADHD into adulthood.
- To determine if these associations are independent of comorbid bipolar disorder (BD).
Main Methods:
- Eighty-one adult ADHD patients, without BD, were categorized into childhood-onset (n=46) and adult-onset (n=35) ADHD groups.
- Severity of ADHD symptoms was assessed using the Wender Utah Rating Scale (WURS-25) for childhood symptoms and Turgay's Adult ADD/ADHD Diagnosis and Evaluation Scale (DES) for adult symptoms.
- Temperamental characteristics were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire (TEMPS-A).
Main Results:
- Adult ADHD patients exhibited higher scores on cyclothymic, irritable, and anxious TEMPS-A subscales compared to childhood ADHD patients.
- Childhood ADHD symptom severity (WURS-25) positively correlated with cyclothymia.
- Adult ADHD symptom severity (DES) positively correlated with cyclothymic, hyperthymic, and irritable temperaments.
- Cyclothymic and irritable temperaments were significantly linked to the severity of adult ADHD symptoms.
Conclusions:
- Cyclothymic and irritable temperaments may serve as predictors for adult ADHD, independent of bipolar disorder.
- These temperamental traits could play a role in the persistence and manifestation of ADHD symptoms in adulthood.

1.0K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

02:18Intrinsically Disordered Proteins
19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

5.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
