These 10 autism symptoms or signs of autism that you should be made aware of because they help your autism characteristics in a person.
It is often a difficult issue to think if someone is on the autism spectrum or not because of so much information about it around.
This is a way of helping you understand ways in which you can confidently identify autism in person quickly and effectively.
Not all of these will apply to every single autistic person, but this is a good overview of potential autism traits in a person.
1 Repetitive Behaviour
2 Eye Contact Issues
3 Non Verbal 4 Delayed Speech
5 Obsessive Interests
6 Lack Of Social Skills
7 Difficulty Relating To People
8 Social Anxiety
9 Bad Executive Function
10 Poor Communication Skills
There are lots of benefits from having an official autism diagnosis like access to help and support in the areas you need it most.
But it is not always simple to know how to diagnose autism. This is why I have made this step by step guide on how to go about getting an official autism diagnosis either for yourself or someone you are helping
STEPS
1 Create a list of all quirks and interesting differences that the person in question does out of ordinary.
2 Take an online AQ test and record the score / print out the results.
3 Call your doctor and ask for an appointment to discuss a referral for autism.
4 Ask your doctor if you can have a referral for an autism assessment based off your list and results.
5 Expect 2-3 assessments in the autism assessment process 6 Observe your results and apply the recommend help and therapy Some cases, in some countries autism assessments can take up to 2 years to book, you can always opt for a private assessment but it probably will cost.
Diabetics exert less force to hold an object than people with other diseases that affect the nervous system. Grip force is a key behavioral biomarker to detect incipient diabetic neuropathy
Grip force is a key behavioral biomarker to detect incipient diabetic neuropathy CREDIT Paulo Barbosa de Freitas Júnior
Research conducted at Cruzeiro do Sul University in São Paulo, Brazil, can contribute to earlier diagnosis of diabetic neuropathy, a disorder characterized by damage to peripheral nerves, with symptoms such as pain and paresthesia (pricking, burning and numbness), mainly in the legs and feet.
In the study, a group led by Professor Paulo Barbosa de Freitas Júnior measured grip force in diabetic patients while they were holding and handling objects. The results were compared with data for healthy subjects and patients with other neurological diseases, such as multiple sclerosis, Parkinson’s, and carpal tunnel syndrome (pain, numbness and tingling in the hand and arm caused by a pinched nerve in the wrist).
Freitas and his group tested volunteers to measure the grip force exerted by diabetics with and without a diagnosis of neuropathy, as well as healthy subjects, and developed a methodology that can be used to produce equipment for use in clinical practice. In future, the innovation should help physicians diagnose the disorder quickly and easily not long after the onset of initial symptoms of neuropathy in diabetics.
The analysis focused on grip force used to hold and manipulate objects, and on relative safety margin, i.e. grip force normalized by the coefficient of friction between skin in contact with the object and surface of the manipulated material. The central nervous system “calculates” the amount of force needed to hold an object, learning to do so better over time. “Every object has a contact surface with which our fingers create friction when we hold it. The smoother the surface, the more grip force needed to hold it. If it’s rough, we can use less grip force thanks to friction,” Freitas explained.
Considering grip force and safety margin, people with neurological disorders such as multiple sclerosis and Parkinson’s tend to use more force to grip objects than healthy people. The force needed to manipulate an object is moderately greater than the minimum force needed to hold it in the desired position. “In the case of people with neurological alterations, our hypothesis is that they grip objects more strongly as a conservative strategy,” Freitas said. “The nervous system detects a neurological deficiency and sends a command for the hand to use more force as it grips the objects. This process is entirely unconscious, of course.”
The test results showed that healthy volunteers used between 100% and 120% of the minimum force required to hold an object, whereas the force used by participants with neurological alterations was two and a half times to three times greater.
Freitas and his team then investigated the performance of diabetics, who typically suffer from neuropathy as the disease worsens. “There was no prior research on diabetics involving the type of experiment we used in our study,” he said.
The hypothesis was that diabetics would grip objects more tightly, as is the case with people who suffer from carpal tunnel syndrome, multiple sclerosis and Parkinson’s. “However, what we found was the opposite: diabetics used half as much force to hold an object as controls in the simplest task, which was the static test, in which the subject merely has to hold an object without manipulating it,” Freitas said.
An article published in the journal Human Movement Science reports the main findings of the study, which was funded by FAPESP via a Regular Research Grant and a scientific initiation scholarship.
Calculating grip force
Three types of test were conducted with 36 volunteers, including 24 diabetics divided into two groups: 12 who had developed neuropathy, and 12 who had neither been diagnosed with neuropathy nor displayed clinical signs of the disorder. The other 12 participants were healthy and formed the control group. Before testing began, the researchers measured each participant’s skin sensitivity, since the sense of touch is a key factor in conveying to the central nervous system the information required by the brain to calculate the force needed to hold and manipulate objects.
Volunteers were each asked to perform three tasks using the same type of object instrumented to measure force. In the static holding test, they had to hold the object with their dominant hand as if they were holding a glass of water. A beep sounded after ten seconds, and they were to unclasp their fingers slowly so as to release the object, while a researcher measured the friction between the fingers and the object. The second task consisted of picking up an object from a table, lifting it about 5 cm, holding it for 10 seconds, and putting it back on the table. In the third task, termed oscillation, the volunteers had to grasp the object, hold it in front of their navel, and move it about 20 cm up and down for 15 seconds.
In the second and third tasks, the results for diabetics and diabetics with neuropathy were similar to those for controls. The surprise came in the simplest task of all, which was static holding, as diabetics and diabetics with neuropathy used half the force applied by the controls.
The explanation is not exactly a loss of sensitivity in the fingers of diabetics, the researchers explained, but deficient tactile information sent from their fingertips to the central nervous system. There is not enough information of high quality for the brain to make the requisite calculations and the hand to use the right amount of force. “In addition, there are studies showing that certain areas of the spinal cord and cortex that receive and process this sensory information are smaller in diabetics than in healthy people,” Freitas said.
The study suggests diabetes does not only affect the periphery of the body, causing loss of sensitivity in the toes and fingers, for example, but also affects the central nervous system. “This happens early in diabetes. People tend to think these complications happen only after a certain age or when a person has had diabetes for some time, but actually patients have the problem before neuropathy is diagnosed,” Freitas said.
Novel device for rapid early diagnosis
Scientists do not fully understand what causes neuropathy in diabetics. One hypothesis has to do with neuron death or loss of function due to alterations in blood vessels and metabolism. “Because of metabolic alterations, blood doesn’t reach the nerve ends in the soles, palms, toes and fingers, leading to the death of neurons in these peripheral regions,” Freitas surmised. As the disease progresses, neurons in other regions closer to the torso, knees and so on, also suffer damage and may die.
Given this lack of knowledge, prevention is the best option, and the study discussed here will help in this regard, according to Freitas. “Our research provides a foundation on which a simple device could be developed for use in the doctor’s office with rapid results,” he said. Grip and load force can serve as behavioral biomarkers to detect neurological alterations even before the patient manifests clear symptoms of neuropathy. “The idea is to have a device that enables physicians to measure force in a straightforward test and see if the patient shows signs of incipient neurological alterations.”
Neuropathy is currently diagnosed by means of a painful invasive examination using a technique called electroneuromyography, in which an electric current is passed through small electrodes in the shape of needles inserted into the patient’s muscles and the reaction time is measured to assess nerve conduction velocity. Freitas proposes a procedure that can be used during a regular visit to the doctor. The patient would hold an object instrumented to measure grip force. “After 10 to 15 seconds of this test, the physician would have the result: the object was held with this or that level of force, and the value measured is below or above the level considered safe to the act of holding the object. It could evidence neurological alterations arising from diabetes,” he said.
The next steps envisaged by Freitas include developing the instrumented object for use in such testing, which could be simpler than the one used in research. To do so, he needs to determine the best combination between the object’s weight and surface smoothness or roughness, so as to evidence the difference between diabetics and nondiabetics. “We need various combinations of smoothness and roughness, as well as lighter and heavier weights, in order to measure the differences between the combinations, and choose the best for use in future tests,” he said. He is pursuing partnerships with hospitals and companies interested in participating in the development of a solution, as well as volunteers for forthcoming studies.

Negative school experiences can have harmful long term effects on pupils with Autism Spectrum Conditions, a new study in the journal Autism reports.
Researchers from the University of Surrey have discovered that experiences of social and emotional exclusion in mainstream schools can adversely affect how pupils with autism view themselves, increasing their risk of developing low self-esteem, a poor sense of self-worth and mental health problems.
Examining 17 previous studies in the area, researchers discovered that how pupils with autism view themselves is closely linked to their perceptions of how other’s treat and interact with them. They found that a tendency of many pupils with the condition to internalise the negative attitudes and reactions of others toward them, combined with unfavourable social comparisons to classmates, leads to a sense of being ‘different’ and more limited than peers.
Negative self-perception can lead to increased isolation and low self-esteem making pupils with autism more susceptible to mental health problems.
It was discovered that the physical environment of schools can impact on children’s ability to interact with other pupils. Sensory sensitivity, which is a common characteristic of autism and can magnify sounds to an intolerable level, can lead to everyday classroom and playground noises such as shrieks and chatter being a source of anxiety and distraction. This impacts on a pupil’s ability to concentrate in the classroom and to socialise with others, further increasing isolation and a sense of being ‘different.’
It was also found that pupils with autism who developed supportive friendships and felt accepted by classmates said this helped alleviate their social difficulties and made them feel good about themselves.
These findings suggest it is crucial for schools to create a culture of acceptance for all pupils to ensure the long term wellbeing of pupils with autism in mainstream settings.
Lead author of the paper Dr Emma Williams, from the University of Surrey, said: “Inclusive mainstream education settings may inadvertently accentuate the sense of being ‘different’ in a negative way to classmates.
“We are not saying that mainstream schools are ‘bad’ for pupils with autism, as other evidence suggests they have a number of positive effects, including increasing academic performance and social skills.
“Rather, we are suggesting that by cultivating a culture of acceptance of all and making small changes, such as creating non-distracting places to socialise, and listening to their pupils’ needs, schools can help these pupils think and feel more positively about themselves.
“With over 100,000 children in the UK diagnosed with autism, it is important that we get this right to ensure that pupils with autism get the education they deserve and leave school feeling accepted, loved and valued, rather than with additional mental health issues”.
