Background:
Hyperactivity disorder and attention deficit are common neurological disorders in children and adolescents. The symptoms of hyperactivity are decreased in adults, and attention deficit is more noticeable. This study was carried out to evaluate the effect of memantine on adult patients with attention deficit hyperactivity disorder (ADHD).
Materials And Methods:
In a double-blind clinical trial study, 40 patients aged 18 to 45 years with ADHD were selected on the basis on the Diagnosis and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria, and randomly assigned memantine or placebo. Before starting the treatment, Conners' screening questionnaire was completed for each patient, and the subjects were entered the study after acquiring minimum acceptable score in the questionnaire.
Results:
The mean age of patients who were receiving memantine and placebo was about 34.7 ± 4.48 and 31.5 ± 7.4 years, respectively. The results have shown a significant difference in the behavior and attention deficit between the two groups treated with memantine and placebo during 6 weeks (p < 0.001). Also, there was a significant difference in the third and sixth weeks between treatment groups in hyperactivity and attention deficit index (p = 0.001).
Conclusion:
The results of this study indicated that memantine was effective in reducing symptoms of Inattention/Memory Problems, Hyperactivity/Restlessness, Impulsivity/Emotional Lability.

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...
01:27Disorders 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.

01:27Disorders 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...
