People with autism sometimes may have physical symptoms, including digestive problems such as constipation and sleep problems. Children may have poor coordination of the large muscles used for running and climbing, or the smaller muscles of the hand. About a third of people with autism also have seizures.
This paper first reviews research which shows that autism impacts many systems in the body, including the metabolic, mitochondrial, immunological, gastrointestinal and the neurological. These systems interact in complex and highly interdependent ways.
Further brain regions commonly display structural and functional abnormalities in ASD, including visual cortical areas, prefrontal cortex (PFC) subregions, caudate nucleus, and putamen subregions of the basal ganglia, hippocampus, sensorimotor cortex, cerebellum, and thalamus [45,46,47,48,49].
In the autistic brain, the brain reduced connectivity, known as hypoconnectivity, allows weakly connected regions to drift apart, with sulci forming between them.” Research has shown the deeper theses sulcal pits are, the more language production is affected.
autistic children often have difficulties with posture, coordination and motor planning. Research consistently shows that autistic children can experience both gross and fine motor delays and/or atypical motor patterns (e.g. Green et al. 2002).
Sensory Issues
Many people with autism experience sensory processing disorder. This is more commonly known as sensory overload. Noise, crowds, bright lights, strong tastes, smells, and being touched can feel unbearable to someone with HFA. This makes going to restaurants, movies, and shopping malls difficult.
Autistic individuals prefer predictability, routines, and patterns, making sudden changes difficult. It bothers them greatly when unexpected changes occur, and they become very upset about it. For instance, HFA individuals may stick with routines developed for them by other people or themselves.
Associative Thinking: Most individuals on the spectrum are associative thinkers rather than linear thinkers. In other words, one thought connects to another and so on through sometimes loose or seemingly irrelevant connections.
For people on the autism spectrum, the world is a bewildering place. With oversensitive sensory systems, they battle to process the maelstrom of information flowing into their brains. Often the result is sensory overload, leading to signature behaviours such as tantrums, anxiety and social withdrawal.
Therefore, it appears that while some individuals may be aware they are autistic, others may not fully understand why they have difficulties connecting with people socially or engaging in conversation - yet still realize they are 'different.
In conclusion, there are many factors that can make autism worse. Sensory overload, changes in routine, social isolation, co-occurring conditions, and lack of support can all exacerbate the symptoms of autism.
difficulties with high-level language skills such as verbal reasoning, problem solving, making inferences and predictions. problems with understanding another person's point of view. difficulties initiating social interactions and maintaining an interaction.
Untreated autism causes changes in brain function that make it more difficult for the person to control impulsive behavior or think rationally about their actions before they act on them. This can lead to situations where ASD adults are unable to live alone and take care of themselves without assistance.
Every autistic person is different, but sensory differences, changes in routine, anxiety, and communication difficulties are common triggers.
High-functioning autism means that a person is able to read, write, speak, and handle daily tasks, such as eating and getting dressed independently. Despite having symptoms of autism, their behavior doesn't interfere too much with their work, school, or, relationships.
Autism affects the amygdala, cerebellum, and many other parts of the brain.
Some characterizations suggest that autistic people do not feel empathy. However, research indicates that rather than lacking empathy, autistic people may have imbalances in empathy skills compared with neurotypical people. ASD is a spectrum disorder.
Autistic people may display a range of strengths and abilities that can be directly related to their diagnosis, including: Learning to read at a very early age (known as hyperlexia). Memorising and learning information quickly. Thinking and learning in a visual way.
Intense interests
Many autistic people have intense and highly-focused interests, often from a fairly young age. These can change over time or be lifelong. It can be art, music, gardening, animals, postcodes or numbers.
People with autism tend to have insomnia: It takes them an average of 11 minutes longer than typical people to fall asleep, and many wake up frequently during the night. Some people with the condition have sleep apnea, a condition that causes them to stop breathing several times during the night.
A few different factors converge to explain why autistic people have an “overly full head” and disorganized thoughts, as well as why we may be scatterbrained, quick to lose oversight, and more prone to overstimulation and dysregulation. All these factors are likely caused by overconnectivity in the brain.
While love is expressed and experienced differently from person to person, those with autism are fully capable of forming deep emotional connections. These can include love for their family, friends, romantic partners, or even interests and hobbies.
However, the fitness tests showed that aerobic fitness, flexibility and body mass index of children with autism spectrum disorders was similar to the children without autism. The strength test was the only one that children with autism spectrum disorders did not perform as well in, the study said.
People with ASD have a reduced perception of their body movement or shift relative to their own postural orientation and equilibrium. At the clinic we often hear of issues such as fatigue, awkwardness, clumsiness and instability of their foot, ankle and hip joints.
