Dandy-Walker malformation

What is Dandy-Walker malformation?

Dandy-Walker malformation is a congenital brain condition that occurs when the two hemispheres of the cerebellum do not form properly. This leads to an increase in cerebrospinal fluid between the fourth ventricle and cerebellum, which in turn causes these areas to be enlarged.

This in turn can then cause hydrocephalus, or an excess of fluid on the brain, generally in the first year of life. Symptoms of this include an increased head size, vomiting, and extreme sleepiness.

Treatment for Dandy-Walker malformation involves a cerebral shunt to drain the excess fluid.

Dandy-Walker can cause issues with movement, coordination, intellectual ability, and other neurological skills.

Symptoms may affect multiple parts of the body. Understanding which part of the body a symptom affects can help us to better understand the potential underlying causes of a symptom, including a rare disease or genetic syndrome.

The brain is the central organ of the nervous system, a system that includes not only the brain but also the sensory organs of the body, the spinal cords, and the nerves that connect them all. The nervous system is how the different parts of the body communicate with each other and control their responses to both internal and external stimuli.

Generally, symptoms affecting the brain can not be seen with the naked eye. Although diagnosing a brain-related symptom may involve different tests and assessments, both subjective and objective.

Symptoms related to the brain may affect other parts of the body and development, including intellectual ability, movement, speech, and other crucial bodily functions.

What should I do next?

In some instances, enlarged Dandy-Walker malformation may be one of the features of a rare disease or genetic syndrome. To find out if someone with Dandy-Walker malformation, may be due to a genetic syndrome, it is important to have a consultation and evaluation with a clinical genetic specialist.  Specialists may also suggest specific genetic testing or other types of tests to help reach a diagnosis.  FDNA’s AI technology can help speed up the diagnostic process by analyzing facial features and other health information.

Signs & Symptoms

Hyperkinetic Movements

Hyperkinetic movements are repetitive, abnormal and involuntary movements of the body. These motions are identified as common neural disturbances in children and can potentially lead to movement disorders. The distribution and severity of these repeated movements may shift over time.

Rieger Anomaly

Reiger anomaly is an ocular defect characterized by serious deformity in the anterior chamber of the eye with noticeable strands and shrinking of the iris stroma. This congenital malformation of the anterior segment is identified by iridocorneal malformation, glaucoma, iris stromal hypoplasia, posterior embryotoxon, and corneal opacities.

Restrictive Behavior

Restrictive behavior is a form of behavior characterized by an abnormal limitation to a few interests and activities. Children may engage in repetitive motor movements or speech and may continually employ the same routine.
