Purpose Of Review:
The purpose of this review is to highlight the origin and evolution of the field of neurodevelopmental disabilities and describe the main construct(s) upon which the current classification of neurodevelopmental disorders is based.
Recent Findings:
We address the following questions: Are neurodevelopmental disorders independent entities? Why is it desirable to understand the neurobiological substrate for these disorders? What new knowledge have we generated by leveraging advances in neuroscience, genetics, and neuroimaging? And finally, is the current construct, that is based on functional classification, still useful?
Summary:
As our biological understanding of brain-behavior disorders evolves, we ought to re-evaluate the current classification system and expand it into a multidimensional classification that takes into account behavioral profiles and underlying mechanisms.

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...
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...
