Acute myelomonocytic leukemia (AMML) is a form of acute myeloid leukemia that involves a proliferation of CFU-GM myeloblasts and monoblasts. AMML occurs with a rapid increase amount in white blood cell count and is defined by more than 20% of myeloblast in the bone marrow. It is classified under "M4" in the French-American-British classification (FAB). It is classified under "AML, not otherwise classified" in the WHO classification.Translocations have been observed. Progression from myelodysplastic syndrome has been reported. Signs and symptoms
Some patients may experience:
Fatigue
Easy Bruising
Abnormal Bleeding
Anemia
Thrombocytopenia
DyspneaIf the blast count gets too high and clog up blood vessels, some patients may experience:
Slurred Speech
Headache
Confusion
Weakness on one side of the body
Sleepiness

Cause
The cause has not yet been determined. It has been said that acute myeloid leukemia can occur from a progression of chronic myelomonocytic leukemia type 1 and 2. Normal red blood cells decrease and a rapid proliferation of the abnormal myeloblasts occur. Apoptosis functional ability decreases which causes a back up of myeloblasts in the bone marrow and blood. AML with a translocation or inversion is seen in different chromosomes. Specifically, AML with inversion in chromosome 16 also known as inv(16) is commonly seen in children. Mechanism
AMML does not have an exact mechanism. The underlying pathophysiology of acute myeloid leukemia consist of maturational arrest of the bone marrow cell during the early stages of development. A myeloblast is an immature precursor cell that will change into a monocyte, healthy white blood cell. In AML, Myeloblast do not mature but grow and multiply with regulation.
ECT is usually indicated for treatment resistant depression, severe vegetative symptoms, psychotic depression, intense suicidal ideation, depression during pregnancy, and catatonia. Psychosurgery is considered experimental but is advocated by some neurologists in certain rare cases.Counseling (professional) and co-counseling (between peers) may be used. Psychoeducation programs may provide people with the information to understand and manage their problems. Creative therapies are sometimes used, including music therapy, art therapy or drama therapy. Lifestyle adjustments and supportive measures are often used, including peer support, self-help groups for mental health and supported housing or supported employment (including social firms). Some advocate dietary supplements.Reasonable accommodations (adjustments and supports) might be put in place to help an individual cope and succeed in environments despite potential disability related to mental health problems. This could include an emotional support animal or specifically trained psychiatric service dog. As of 2019 cannabis is specifically not recommended as a treatment. Epidemiology
Mental disorders are common. Worldwide, more than one in three people in most countries report sufficient criteria for at least one at some point in their life. In the United States, 46% qualify for a mental illness at some point. An ongoing survey indicates that anxiety disorders are the most common in all but one country, followed by mood disorders in all but two countries, while substance disorders and impulse-control disorders were consistently less prevalent. Rates varied by region.A review of anxiety disorder surveys in different countries found average lifetime prevalence estimates of 16.6%, with women having higher rates on average.
