Dandy-Walker Syndrome

Research into the intricate workings of typical cognitive development is a major focus of the National Institute of Neurological Disorders and Stroke (NINDS) as well as its funded projects. Scientists are analyzing DNA samples taken from people with the disorder to help comprehend the origins of the Dandy-Walker condition, uncover the chromosomes implicated in the illness, and create improved diagnostic and therapeutic tools. Several studies have shown that pregnant women with diabetes and rubella were more likely to have a baby with Dandy-Walker disease.

What is Dandy-Walker Syndrome?

Dandy−Walker disease, as well as Dandy−Walker deformity, is a congenital disorder. Genetic brain malformations disrupt normal brain development from birth. Because of how it manifests throughout childbirth, this illness is considered hereditary and affects the child. The brain and surrounding areas play an important role in the game of dandy walker. The cerebellum may be found at the base of the medulla at the rear of the head. A component of the brain and spinal cord. The brain coordinates actions.

Symptoms of Dandy-Walker Syndrome

Quite often, the onset of signs is impactful and unexpected. Sometimes children will show signs, and their parents will not suspect anything is incorrect. While many kids are diagnosed by age 3, others may not be identified until they are 4. Signs typically appear in the first few weeks of life.

  • Arriving at motor checkpoints after than intended.

  • Head size is disproportionate to the rest of the body.

  • Weakness in the muscular tissue.

  • Rigid muscles

  • The rear of the head is swollen or enlarged.

  • Neurological disorders affect the head, neck, and/or vision.

  • Strange breathing pattern.

  • Paroxysmal.

  • Impairments of mental capacity.

  • Manifestations of hydrocephalus.

Effects of Dandy-Walker Syndrome

Symptoms include a bulging of the fourth ventricle. When cerebrospinal fluid travels through this area, it helps connect the brainstem to the brainstem.

  • The cerebellar sulcus, which normally connects the two cerebellar chambers, is missing or severely underdeveloped.

  • Next to the lateral ventricles, a liquid sac develops.

  • The brain base widens.

  • If CSF accumulates, it may cause hydrocephalus, a condition characterized by increased intracranial pressure and brain enlargement.

Dandy-Walker Complex and Dandy-Walker Syndrome

Isolated Cerebral − Reduced size or underdevelopment of the cerebral vermis. Any other brain lesions do not accompany Dandy-Walker disease in developing minds. Many kids who are given this prognosis grow up quite fine.

Mega Magna − Even though the cerebellum is average size, the anterior fossa is rather big. In most cases, mega venue magnum has no potential hazards.

Diagnosis of Dandy-Walker Syndrome

Diagnostic radiological results for Dandy−Walker syndrome. It may be identified as prenatal development on imaging as soon as 12 weeks. However, it is generally confirmed early postnatal by MRI. Only 39% of cases are identified within the first year of birth, often because of worsening indications of hydrocephalus; 27% of cases are identified in adolescence or adulthood owing to mental health disorders like schizophrenia or mental issue.

Causes of Dandy-Walker Syndrome

When the brain does not form properly during pregnancy, the result is a child unable to walk normally. A gene variant may be at the root of the problem in some people. Additional or absent genetic segments have been found in some patients with Dandy−Walker. Genetics are contained in chromosomal, which are packets of DNA. The Dandy−Walker disease has been linked to a hereditary condition that causes many congenital anomalies.

Treatment of Dandy-Walker Syndrome

Dandy−Walker disease therapy is centered on symptom management. Before actually beginning therapy, a medical professional should do a thorough examination. Specifically, medical professionals may advise −


It is always recommended to take only the prescribed medicines from the doctor. In this or any condition, no one should take a medicine that has not been prescribed.


Working with a therapist in occupational and physical therapy may allow children to keep physically active. Kids may learn new ways to accomplish their everyday tasks with the help of their counselors. A person's linguistic potential may benefit through talk therapy. There is a great deal of disagreement on which terminology or standards to diagnose DWM, and there is no consensus on the diagnosis parameters and categorizations. Cerebellar vermis microcephaly and a dilated fourth ventricle with downstream fossa are the main diagnostic requirements for DWM. However, the exact amount of aplasia and cystic expansion for diagnosing DWM is debatable. Diagnosis has been further complicated because DWM and several related disorders have now been placed on a spectrum by certain writers and isolated as independent entities by others.

In particular, if hydrocephalus is prevalent, timely and successful therapy is essential to the outcome. The existence of concomitant hereditary defects or cerebral abnormality is another significant influence on the outcome. About 1 in 14 people will die from DWM. Dandy-Walker variation had an 11% fatality rate in the research. Hydrocephalus and its therapy often lead to fatal consequences. The swelling within the skull rises and eventually harms the brain if hydrocephalus is not corrected. Although shunts are generally effective in treating DWM, there is a marginally greater chance of failure associated with using them, which may lead to complications, including pneumonia or an inability to successfully lower intraocular pressure.


The severity of your medical situation determined your prognosis and expected lifespan, and the presence of other congenital anomalies impacts your outlook. What it is like to live with the illness might vary greatly from person to person. Many only have mild symptoms, and however, some are severely impaired. With the appropriate therapeutic approach, some kids with autism may catch up to their cognitively average peers. Nevertheless, some don't, and when the medical team catches and cures it in time.
