Objectives:
This study aimed to evaluate the impact of comorbid attention deficit hyperkinetic disorder (ADHD) on Bipolar disorder (BD).
Methods:
Patients aged 13-40 years with diagnosis of BD with ADHD (N = 30) were compared to those with BD without ADHD (N = 69) for clinical course, functional outcome and quality of life.
Results:
Those with BD + ADHD had significantly lower age of onset of BD (p < 0.001), a significantly higher number of total lifetime episodes (p = 0.002), higher number of lifetime manic episodes (p = 0.008), higher number of hospitalizations (p = 0.004) and higher prevalence of family history of BD as compared to those with BD without ADHD (p = 0.043). BD + ADHD group had poor response to conventional mood stabilizers and significantly higher prescriptions of atypical antipsychotics (p = 0.001) and higher rates of antidepressant-induced switch. Also, BD + ADHD group had significantly lower level of functioning in personal, occupational and social domains and reduced quality of life. In the BD + ADHD group, 40% patients had persistence of ADHD into adulthood. Comorbid current ADHD had more negative impact on the course and outcome of BD, when compared with those with ADHD in the past.
Conclusions:
Comorbid ADHD has negative impact on the course and outcome of BD.

Bone Disorders
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
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.

Disorders of Leukocytes
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...
