Emotional and behavioral disorders in the context of "Self-contained classroom"

Special education (also known as special-needs education, aided education, alternative provision, exceptional student education, special ed., SDC, and SPED) is the practice of educating students in a way that accommodates their individual differences, disabilities, and special needs. This involves the individually planned and systematically monitored arrangement of teaching procedures, adapted equipment and materials, and accessible settings. These interventions are designed to help individuals with special needs achieve a higher level of personal self-sufficiency and success in school and in their community, which may not be available if the student were only given access to a typical classroom education.

Special education aims to provide accommodated education for students with disabilities such as learning disabilities, learning difficulties (such as dyslexia), communication disorders, emotional and behavioral disorders, physical disabilities (such as osteogenesis imperfecta, down syndrome, lissencephaly, Sanfilippo syndrome, and muscular dystrophy), developmental disabilities (such as autism spectrum disorder, and intellectual disabilities) and other disabilities. Students with disabilities are likely to benefit from additional educational services such as different approaches to teaching, the use of technology, a specifically adapted teaching area, a resource room, or a separate classroom.

Folate deficiency, also known as vitamin B₉ deficiency, is a low level of folate and derivatives in the body. This may result in megaloblastic anemia in which red blood cells become abnormally large, and folate deficiency anemia is the term given for this medical condition. Signs of folate deficiency are often subtle. Symptoms may include fatigue, heart palpitations, shortness of breath, feeling faint, open sores on the tongue, loss of appetite, changes in the color of the skin or hair, irritability, and behavioral changes. Temporary reversible infertility may occur. Folate deficiency anemia during pregnancy may give rise to the birth of low weight birth premature infants and infants with neural tube defects.

Not consuming enough folate can lead to folate deficiency within a few months. Otherwise, causes may include increased needs as with pregnancy, and in those with shortened red blood cell lifespan. Folate deficiency can be secondary to vitamin B₁₂ deficiency or a defect in homocysteine methyl transferase that leads to a "folate trap" in which is an inactive metabolite that cannot be recovered. Diagnosis is typically confirmed by blood tests, including a complete blood count, and serum folate levels. Increased homocysteine levels may suggest deficiency state, but it is also affected by other factors. Vitamin B₁₂ deficiency must be ruled out, if left untreated, may cause irreversible neurological damage.
