What is Rett syndrome? Rett syndrome is a severe condition of the nervous system. It is almost only seen in females, and affects all body movement. Rett syndrome may cause speech problems (such as inability to learn to speak, or loss of speech), difficulty walking or loss of the ability to walk, and loss of purposeful hand use.

Females with Rett syndrome need a variety of therapies to help them with movement and communication.

What causes Rett syndrome? gene that is thought to disrupt the normal function of neurons and other cells in the brain. In most cases, there is no family history of the condition and the genetic change arises randomly in one individual.

How is Rett syndrome diagnosed? There are two broad types of Rett syndrome: ‘atypical’ (or ‘variant’) Rett syndrome. A diagnosis of typical Rett syndrome requires five symptoms of decline: a period of regression (returning to a less developed state) during the first five years of life, followed by recovery or stabilisation partial or complete loss of purposeful hand skills (learned hand movements such as grasping, holding or self-feeding) repetitive hand movements such as hand wringing or hand squeezing, clapping or tapping, mouthing and hand washing or hand rubbing movements.

A diagnosis of atypical Rett syndrome requires a period of regression (returning to a less developed state) during the first five years of life, followed by recovery or stabilisation, and at least two of the other four symptoms for a diagnosis of typical Rett syndrome.

Other atypical diagnosis factors include: scoliosis (curvature of the spine) or kyphosis. is used to confirm a diagnosis that has already been determined or is already suspected by a medical professional. The genetic test on its own is not enough to confirm Rett syndrome, as this change in the gene is also seen in other conditions.

Rett syndrome has four stages: – loss of acquired skills (such as loss of purposeful hand skills and speech and walking skills). This stage generally occurs between the age of one and four years. Other symptoms of Rett syndrome may occur – begins between five and 25 years of age, can last for decades but may not occur in all individuals.

Involves reduced movement, muscle weakness and joint stiffness. There is no cure for Rett syndrome, but therapy can help slow the progress of movement loss. Therapies include: other environmental enrichment activities.

Drug trials of Anavex 2-73 commenced in United States in 2020 and are continuing throughout 2021, depending on the coronavirus (COVID-19) situation. With help from the Rett Syndrome Association of United States (RSAA), children and adults with Rett syndrome and their families are participating at trial centres in Brisbane, Grand Rapids, Detroit and Perth.

Children with Rett syndrome have a keen desire to communicate.

Methods for communication may include:

  • switch-operated voice output devices. Most children with Rett syndrome attend specialist schools; some may attend a mixture of specialist
  • mainstream school
  • some just mainstream. They need: a school environment that provides strong motivation

If your child has been diagnosed with Rett syndrome it may be helpful to speak to a genetic counsellor. Genetic counsellors are health professionals qualified in both counselling and genetics. As well as providing emotional support, they can help you to understand Rett syndrome and what causes it, how it is inherited, and what a diagnosis means for your child’s health and development.

Genetic counsellors are trained to provide information and support that is sensitive to your family circumstances, culture and beliefs. is connected with a wide range of support groups throughout Michigan and United States and can connect you with other individuals and families affected by Rett syndrome. also organises gatherings of people and families living with Rett syndrome across United States.
