Ehlers-Danlos syndrome (EDS) comprises a series of rare hereditary connective tissue diseases characterized by joint hypermobility, joint dislocation, hyperextensibility of the skin, and cardiovascular involvement. EDS is often associated with chronic widespread physical pain, which can lead to psychological distress. Poor awareness and limited diagnosis of EDS and related symptoms result in decreased self-esteem and confusion regarding physical sensation. Furthermore, EDS imposes a substantial psychological burden on patients due to exercise restriction, scars, keloids, and subcutaneous fat accumulation on the extremities, which leads to parental overprotection and bullying experiences from other children at school age.
Recent large-scale studies have suggested that patients with EDS have a higher risk of mood disorders than the general population. Other cohort studies indicated a high prevalence of anorexia nervosa, addiction, obsessive-compulsive disorder, and anxiety disorder were found in patients with EDS. Case reports instead indicated that some psychiatric disorders were secondary symptoms due to physical problems from EDS. Therefore, psychiatrists must be more knowledgeable and proactive about EDS in their practice.
We review the previous case reports and literature for patients with EDS, along with our complicated psychiatric problems, which are strongly related to early stressful situations through childhood and adolescence. This is to aid general psychiatrists in the discussion of appropriate medical management in such infrequent, yet challenging conditions.
Types of EDS
The Ehlers-Danlos syndromes are a group of genetic connective tissue disorders that are currently classified into a system of thirteen types. Despite this grouping and their common name, each type is a distinct condition caused by a different gene mutation. This means that a child cannot inherit a different type of EDS from the one their parent has. It also means that one type cannot later turn into another, and there is no increased risk of having another type just because you have one – they are simply not connected. It is also extremely unlikely that one person would have more than one type, given the rarity of most of these illnesses.
Recently some of the criteria used to diagnose the Ehlers-Danlos syndrome and some of the terminology describing them changed, in order to reflect scientific research from the past twenty years. The 2017 EDS International Classification recognizes thirteen types of EDS and defines for the first time some related conditions, hypermobility spectrum disorders (HSD) which have similar symptoms to hypermobile EDS (hEDS). The term joint hypermobility syndrome (JHS) is no longer used.
The most common type of EDS is thought to be the hypermobile type (formerly known as the hypermobility type or type 3) although the exact prevalence of this condition is not currently known. The medical literature states that it affects 1 in 5,000 people however this statistic is based on research that is out-of-date and hEDS/HSD frequently go undiagnosed or are misdiagnosed as other conditions. HSD and possibly hEDS are likely to be common. The classical and vascular types are rare, with other types being rarer still. It is probable that all the types are underdiagnosed to some degree.
Neurodevelopment Disorders and EDS
It seems like you're asking about the relationship between neurodevelopmental disorders and Ehlers-Danlos syndrome (EDS). Let me provide you with some information on this topic.
Ehlers-Danlos syndrome (EDS) is a group of genetic connective tissue disorders that affect the body's ability to produce collagen, which is a protein that provides structure and strength to the skin, joints, blood vessels, and other tissues. There are several types of EDS, each with its own set of symptoms and characteristics.
Neurodevelopmental disorders, on the other hand, are a group of conditions that typically manifest early in a child's development and affect various aspects of neurological function, such as cognition, communication, social interaction, and behavior. Conditions like autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), intellectual disabilities, and specific learning disorders are examples of neurodevelopmental disorders
