Exploring Life Expectancy for Level 3 Autism

Understanding Autism Life Expectancy

Life expectancy in individuals with autism spectrum disorder (ASD) is a complex topic with various influencing factors. This section seeks to provide an overview of autism life expectancy and the factors that may affect it.

Overview of Autism Life Expectancy

Autism life expectancy varies greatly depending on multiple factors, including the severity of autism and the presence of other health conditions. According to the National Library of Medicine, the average autism life expectancy in 2018 fell as low as 39 years [1].

However, another study suggests that the average autism life expectancy was around 54 years old, which is still lower than the 72-year life expectancy for the general population.

It's important to note, these studies represent averages, and individual experiences can vary significantly.

Factors Affecting Life Expectancy

Several factors can affect the life expectancy of individuals with autism. One study found that over a 20-year period (1998-2018), 6.4% of individuals with ASD died at an average age of 39 years, which is 38.5 years prior to their life expectancy. Causes of death included chronic conditions, accidents, and health complications due to medication side effects.

Moreover, longitudinal studies have found that those with more severe forms of Autism, such as level 3 autism, tend to have a shorter life expectancy [3].

Another critical factor is the risk of injuries. Autistic individuals are three times more likely to die because of injuries than the general population [1].

Understanding these factors is crucial in developing strategies and interventions to improve the life expectancy and overall well-being of individuals with autism.

Research Insights on Autism Life Expectancy

Gaining a comprehensive understanding of autism life expectancy requires a thorough examination of the available research. This exploration will provide an overview of various studies conducted on this subject and the factors contributing to mortality in autistic individuals.

Studies on Autism Life Expectancy

A matched cohort study conducted in the UK provided critical insights into the life expectancy and years of life loss for individuals with autism. A different study marked the average autism life expectancy at around 54 years, which is still significantly lower than the general population's 72-year life expectancy [1].

Longitudinal studies have found that the average life expectancy for individuals with autism ranges between 39 and 58 years. Those with more severe forms of autism, such as level 3 autism, are likely to have shorter life spans.

Mortality Causes in Autistic Individuals

Looking at mortality causes, research indicates that individuals with autism are three times more likely to die from injuries than the general population. Moreover, they are six times more likely to attempt suicide and up to seven times more likely to die by suicide.

Over a 20-year period (1998-2018), 6.4% of individuals with autism spectrum disorder (ASD) died at an average age of 39 years, which is 38.5 years prior to their life expectancy. Causes of death included chronic conditions, accidents, and health complications due to medication side effects.

Understanding these mortality causes can play a pivotal role in formulating strategies to improve the life expectancy of individuals with autism and ensuring they receive requisite care and support.

Levels of Autism and Life Expectancy

The life expectancy of individuals with autism can vary significantly depending on the level of autism. Autism is classified into three levels based on the severity of symptoms and the level of support required. Let's explore the life expectancy associated with each level of autism.

Level 1 Autism Life Expectancy

Individuals with Level 1 Autism, which requires minimal support, have the highest life expectancy of the three levels of Autism. Their life expectancy falls slightly below the average life expectancy of the general population. A recent study conducted in the United Kingdom found that men with Autism have an estimated life expectancy of 72 to 75 years, and women with Autism have an estimated life expectancy of 70 to 77 years [3].

Level 2 Autism Life Expectancy

Moving on to Level 2 Autism, which is moderately affected, individuals typically have a life expectancy ranging from 50 to 60 years, slightly lower than Level 1. This decrease in life expectancy can be attributed to the increased support requirements and potential comorbid health conditions associated with Level 2 Autism.

Level 3 Autism Life Expectancy

The most severe form of autism, Level 3 Autism, presents the greatest challenges. Individuals with Level 3 Autism, who are typically nonverbal and have difficulty understanding communication and socializing, may have a life expectancy as low as 35 to 40 years old. Longitudinal studies have found that the average life expectancy for individuals with Autism ranges between 39 and 58 years. Those with more severe forms of Autism, such as Level 3, have a shorter life expectancy.

While these figures provide some insight into the life expectancy of individuals with different levels of autism, it's important to remember that they are averages and can vary significantly on a case-by-case basis. Many factors can influence life expectancy, including the individual's overall health, access to healthcare, and the presence of any co-occurring conditions.

Risk Factors for Premature Death

When considering level 3 autism life expectancy, it's crucial to assess the potential risk factors that can contribute to premature death. This includes both accidents and injuries, as well as various neurological disorders that are often associated with autism.

Accidents and Injuries

Accidents, including drowning, are the number one cause of premature death for autistic people. Individuals on the spectrum are three times more likely to die from injuries than the general population. This alarming statistic reveals the critical need for increased safety measures, appropriate supervision, and potentially lifesaving skills such as swimming for individuals with autism.

Neurological Disorders in Autism

Autistic individuals are at an increased risk of various neurological disorders, which can also lead to premature death. These disorders include epilepsy, hydrocephalus, sleep disorders, and gastrointestinal disorders. Each of these conditions requires specific medical attention and care, and their presence in individuals with autism can complicate the overall health scenario.

Epilepsy, for example, is more common in children with autism spectrum disorders (ASD) than in the general population. Similarly, sleep disorders are significant problems in individuals with autism, occurring in about 80% of them.

Gastrointestinal (GI) disorders are also more common in children with ASD; they occur in 46% to 84% of them. The most common GI problems observed in children with ASD are chronic constipation, chronic diarrhea, gastroesophageal reflux and/or disease, nausea and/or vomiting, flatulence, chronic bloating, abdominal discomfort, ulcers, colitis, inflammatory bowel disease, food intolerance, and/or failure to thrive [4].

Additionally, several categories of inborn-errors of metabolism have been observed in some patients with autism including mitochondrial disorders, disorders of creatine metabolism, selected amino acid disorders, disorders of folate or B12 metabolism, and selected lysosomal storage disorders.

Furthermore, genetic disorders such as Down Syndrome, muscular dystrophy, and Fragile X syndrome can contribute to a lower life expectancy of autistic individuals [1].

The presence of these various neurological and genetic disorders highlights the complexity of managing health in individuals with autism, and the significant role these conditions play in affecting life expectancy. Awareness and understanding of these risk factors are crucial in managing health outcomes and improving the quality of life for those with autism.

Improving Life Expectancy in Autism

While the life expectancy for those with autism, particularly level 3 autism, can be influenced by various factors, research has shown that there are ways to potentially improve this prognosis. These methods primarily involve early intervention programs and supportive services for autistic individuals.

Early Intervention Programs

Early intervention programs have been found to significantly improve an individual's prognosis and enhance overall quality of life [3]. These programs are designed to address the core symptoms of autism at a young age, enhancing the child's development and providing them with the tools necessary to navigate life more effectively.

Moreover, early diagnosis combined with access to evidence-based early intervention programs can significantly enhance overall quality of life for individuals with autism.

Notably, interventions that address impairments in social reciprocity may have long-term effects on survival. By improving social interaction skills, these programs can help autistic individuals form meaningful relationships and integrate more effectively into society.

Initiatives that improve physician awareness in screening and diagnosis of young children also show promise in delivering the best care to individuals with Autism Spectrum Disorder. Enhanced screening and diagnosis can lead to earlier and more effective interventions, potentially contributing to improved life expectancy.

Supportive Services for Autistic Individuals

Beyond early intervention programs, supportive services for autistic individuals can also contribute to improving life expectancy. These services span a wide range, from access to quality healthcare to educational support and vocational training.

Access to healthcare, in particular, can make a significant difference in the life expectancy of autistic individuals [5]. Regular health check-ups, mental health support, and specialized care for co-occurring conditions can all contribute to a longer and healthier life.

Moreover, educational support can equip autistic individuals with the skills needed to lead independent and fulfilling lives. Vocational training, on the other hand, can provide opportunities for employment and community involvement, both of which have been linked to improved quality of life and longevity.

In conclusion, while the life expectancy of those with level 3 autism can be influenced by various factors, early intervention programs and supportive services can play a significant role in improving this prognosis. These strategies highlight the importance of early diagnosis, comprehensive care, and societal support in enhancing the lives of those with autism.

Access to Healthcare for Autistic Individuals

Life expectancy for individuals with Level 3 Autism can be significantly influenced by the quality and accessibility of healthcare services. However, several barriers can hinder access to these necessary health services, and initiatives are underway to address these challenges.

Barriers to Healthcare Access

Families living outside metropolitan areas often experience less access to care for Autism Spectrum Disorder (ASD) than those in urban areas. The reason for this disparity is often due to a shortage of specialists. For instance, in the USA, the number of child and adolescent psychiatrists per 100,000 ranges from 5 in Idaho to 60 in the District of Columbia. This disparity results in a service supply shortage, clinician burnout, and long wait times for diagnosis and treatment [5].

On top of geographical barriers, the cost of healthcare can also pose a significant barrier. According to NCBI, annual healthcare costs for individuals with ASD in the USA increase with age, ranging from USD 6,467 for ages 0-5 to USD 13,580 for ages 18 and above. The cost increases significantly for those with co-occurring intellectual disability.

Lastly, stigma and lack of awareness can also hinder access to healthcare. Reduced awareness of ASD and related services is more common in groups with lower socioeconomic status, less education, and limited access to health professionals. Furthermore, stigma can contribute to feelings of rejection and isolation among parents of autistic children and can prevent individuals with ASD from engaging with the healthcare system at all stages of life.

Initiatives to Improve Healthcare Services

To overcome these barriers, several initiatives are underway.

To address the issue of physician knowledge and training, initiatives that improve physician awareness in screening and diagnosis of young children show promise [5].

To help with the financial burden of healthcare, insurance coverage is being promoted as a way to address the financial barrier to accessing healthcare.

Public awareness campaigns are also being launched to increase understanding of ASD and encourage individuals and families to seek healthcare services.

Finally, to combat stigma, initiatives that reduce stigma and increase knowledge and acceptance of ASD are being implemented. These initiatives aim to improve access to healthcare, particularly for racial/ethnic minorities who are often most affected by stigma [5].

While these initiatives are a step in the right direction, more work is needed to ensure that all individuals with ASD, including those with Level 3 Autism, have access to the quality healthcare services they need.
