Auitsm and Echopraxia

Greetings Earthlings! 🙂

Leading on from my previous post on echolalia, this week I’d like to briefly discuss the phenomenon echopraxia.

Yes I know, it’s another mouthful, but what exactly is echopraxia?

Echopraxia (also known as echomotism or echokinesis) is a type of tic disorder characterized by involuntary imitation of another persons actions e.g. waving a hand, touching your nose, kicking something, even facial expressions. Echopraxia is one of the core features of Tourette’s syndrome, however it has also been found to occur in ASD’s. It is often paired with echolalia, but it has been known to occur independently in autists.

I know what you’re thinking- imitation of actions is critical to early development in childhood and perfectly “normal” behaviour, so it seems like echopraxia might be reading into things too much. However, when this behaviour persists and becomes reactionary rather than a learning tool, then it can be viewed from a pathophysiological  perspective. As such, it can be very difficult to diagnose this behaviour in children. 

So what does the science have to say about echopraxia and autism?

There’s very limited research in this area, however experts believe that echopraxia is related to damage or dysfunction within the frontal lobe known as the action cortex of the brain- an area that is often implicated in autistic behaviours. Other’s have theorized that abnormalities in the mirror neurons located here may be responsible.

Nope, I’m afraid mirror neurons are not quite this exiting- mirror neurons are in fact a particular type of nerve cell that fires when a person or an animal acts and witnesses another person complete the same action. This type of behaviour has been particularly observed in primates, giving new meaning to the phrase ‘monkey see, monkey do’.

In general, echopraxia is considered harmless, however if it starts to interfere with social functioning, then behavioural modifications, medications and psychotherapy are possible treatment options 🙂

Autism on Screen- What’s Eating Gilbert Grape

Greetings Earthlings! 🙂

This week I’d like to discuss the portrayal of autism in the 1993 comedy-drama film ‘What’s Eating Gilbert Grape‘ starring Johnny Depp, a young Leonardo Dicaprio and Juliette Lewis (who ironically portrayed an autistic character in ‘The Other Sister‘ a few years later).

The story follows Gilbert Grape (Depp) a young man living in a rural town in Iowa as he takes care of his obese mother and autistic brother Arnie (Dicaprio). The film explores Gilbert’s life and struggles to take care of his family whilst trying to forge a life of his own.

If you haven’t seen this classic, here’s the trailer:

So how does the film fare in it’s depiction of autism?

Autism is not explicitly mentioned as such in this film, but most experts agree that Arnie’s traits align with those of autism. His repetitive movements, echolalia, self injurious behaviours, use of atypical speech, preference for routine, his childlike nature, mind-blindness and lack of danger perception (he has a fondness for climbing the town water tower) all indicate that Arnie is on the spectrum. This is also one of the few films where the autist is not portrayed as a savant so that’s a refreshing change!

Leonardo Dicaprio’s acting is, as always, sublime- he even received his first ever Academy Award nomination for his portrayal of Arnie in this role. In particular I felt that the depiction of meltdowns was quite good, however, the most striking aspect of the film, as in Atypical, was how it highlights the struggles that the wider family often experiences with autism, particularly where siblings are concerned. Gilbert loves Arnie dearly, but taking care of him and his entire family takes it’s toll.

The film also takes a more lighthearted approach at times to Arnie’s eccentricities. Arnie’s lack of filter delivers some of the more humorous moments in the film, which like Atypical, allows us to see the funnier side of autism- yes autism can be challenging, but it’s not all doom and gloom.

All in all ‘What’s Eating Gilbert Grape‘ gives a fairly decent representation of autism, but either way- the film is worth a watch just for Leonardo Dicaprio’s performance. This film really was a sign of things to come for him! 🙂

Autism and Catatonia

Greetings Earthlings! 🙂

So this week I’d like to talk about a rare condition that affects approximately 12-18% of autistic adults- autistic catatonia.

But what exactly is this when it’s at home?

Autistic catatonia is a neuropsychiatric condition that causes abnormalities in behaviours, speech and motor functions with varying degrees of severity. In other words, it’s a form of autistic breakdown- one that is often misdiagnosed.

There are over 40 symptoms associated with the condition, many of which overlap with autistic symptoms and traits, so it can be quite challenging to diagnose- even for the most experienced professionals in the field. Symptoms may include mutism, hyperactivity, immobility, stupor, agitation, odd repetitive movements and echolalia. Due to the overlap in symptoms, it’s thought that this condition may be far more prevalent among autists than we realize.

But what causes it?

As with autism, it’s cause too remains a mystery, however it is thought that vitamin deficiencies, trauma, infection and co-morbid disorders such as schizophrenia and biopolar disorder may contribute to it.

So how do we treat it?

There are currently no cures for autistic catatonia, however a number of therapies have been used to manage symptoms such as antidepressants, muscle relaxers, benzodiazapines (such as Lorazepam) and anti psychotics. Electroconvulsive therapy (shock therapy), brain stimulation and NMDA receptor antagonists (a class of anesthetic drugs that are often used recreationally e.g ketamine, nitrous oxide, PCP and the heroin substitute methadone) have also been controversially used to treat catatonia.

There is limited research in this area at present as to how best to treat autistic catatonia, however a psychological approach to treat underlying stress and anxieties which may trigger catatonia is thought to be the best.

Whilst there is no cure, as in the case of autism, with early detection and intervention the condition can be managed 🙂

Autism and Echolalia

Greetings Earthlings! 🙂

This week we’re going to talk about something that effects approximately 75% of autists- Echolalia.

Image result for what in the world gif

I know, I know, it’s a mouthful- but echolalia is actually quite simple:

Echolalia is the meaningless repetition of noises, words or phrases immediately after their occurrence (although sometimes this can be delayed).

Derived from Greek echo, “to repeat,” and laliá, meaning “talk” or “speech,” Echolalia is an automatic and unintentional behaviour.  In most cases Echolalia is used in an attempt to communicate, practice or even learn language. In fact, Echolalia is part of normal development- every child experiences Echolalia when they learn a spoken language.

However, whilst “normal”, this behaviour can persist for longer in autists.

But why might this be?

Psychologically speaking, Echolalia is considered by some to simply be a repetitive or self-stimulatory behaviour in autists (as some experience this behaviour only when they are stressed), however, the general school of thought is that it is a communicative behaviour. Imitative behaviour is an essential part of social learning. As autists struggle so much socially, this imitative behaviour can act as a tool to help improve their social skills.

I’ve certainly exhibited such imitative behaviour during my formative years. For example, I somehow got it into my head that in my final year of primary school I needed to practice my swearing so that I would better be able to fit in when I made the jump to secondary school! 😬🙈 Wasn’t especially successful- sure I could swear like a sailor, buuuuuut it didn’t do much to improve my social skills or status (but I suppose I sounded a little less like a walking thesaurus for a change! 😛 ).

On the biological side of things, much of the physiology of Echolalia remains to be explored, however, one study indicates that the ITGB3 gene (which carries the information for β3 integrin- a cell membrane protein that will interact with other proteins to trigger a number of biochemical reactions in our cells) seems to link autism and echolalia.

There we have it now Earthlings I hope you enjoyed this post! 🙂

Have a lovely weekend everyone! 😀
