Hey my chosen topic is topic one i did research on methylphenidate or more commonly sold on the brand name ritalin and its effect on children specifically on their working memory in this presentation i aim to talk about the effects of mental fatigue on children diagnosed with adhd and whether or not it affects their working memory but to begin i want to clarify

Key terms i’ll be using throughout the presentation let’s start off with adhd what actually is adhd adhd otherwise known as attention deficit or hyperactive disorder is one of the more common neurodevelopmental disorders and is often found to be much more common in children it is usually first diagnosed in childhood and often lasts much later in adulthood is

Often characterized by traits such as being unable to steal constant fidgeting being unable to concentrate on tasks impulsiveness and much more as the traits are often seen to be not very favorable adhd sometimes has a negative connotation and can sometimes be considered disability thus medications such as methylphenidate or more commonly sold under the brand

Name ritalin is often prescribed to these diagnosed with adhd so what actually is methylphenidae it’s a central nervous system stimulant meaning it affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control thus making it effective and treating the symptoms commonly expressed in individuals with adhd my first thoughts is a

Research report straight from straight out of the journal of child psychology and psychiatry volume 48 issue 9. this experiment aimed to investigate the effects of methylphenides are components of working memory in attention-deficit hyperactive disorder and determine the responsiveness of working memory measures to methylphenidate this experiment had a sample size

Of 50 children in a children and adolescents clinically diagnosed with adhd from ages 6 to 16. working memory in these individuals were tested in four main categories which varied in processing demands and modality the results of the experiment conducted show that showed that methylphenidate improved the ability to store visual spatial information irrespective of

Instrument use but had no effect on the storage of auditory verbal information however on the other hand methylphenide enhanced the ability to manipulate both auditory verbal and visual spatial information although effects result sorry although effects were instrument specific in both cases the results of this experiment support the idea that mesophanate does in fact

Have an effect on working memory in children diagnosed with adhd table shows the means and standard deviations for poor performance of each of the working memory measures across methylphenidate dose for the entire sample my second source is a meta-analysis from the journal clinical psychology review the meta-analysis was focused on the efficacy of methylphenidate

Psychosocial treatments and a combination in school-aged children with adhd the results concluded that both methylphenidate and psychosocial treatments were effective in reducing adhd symptoms however psychosocial treatments yielded smaller effects in the effects yielded by the use of methylphenidate in the age range of children from 6 to 12. the results also

Show that in combination psychosocial treatments has no additional value to methylphenidate for the reduction of adhd symptoms this table shows the number of studies total number of participants total weighted mean effect sizes confidence intervals and some other stuff is on the results of this meta-analysis again supports the idea that methylphenidate does in

Fact have an effect on working memory in children diagnosed with adhd although methylphenidate often is considered one of the first treatments for adhd due to its efficacy my third source shows that unfortunately this medication is only effective for some children with adhd this is as genetic factors may contribute to individual differences of the efficacy of drug

Therapy in this meta-analysis it is highlighted that pharmacology studies prove that dopamine and norepinephrine are involved in adhd symptoms thus methylphenidate is often is commonly used as a psychostimulant for the treatment of adhd and is often effective at it as it blocks the dopamine and norepinephrine transporter and causes synaptic concentration of those

Neurotransmitters to increase however as previously mentioned approximately one-third of patients do not respond adequately to stimulant treatment this meta-analysis aims to understand the difference in effect of methylphenidate between individuals with different levels of hormones specifically dopamine and norepinephrine the results concluded that there was a

Direct correlation between the presence of certain gene polymorphisms and the impact of methylphenidate response this table shows the results of different gene polymorphisms and side effects of methyl sorry methylphenidate there are a variety of pros and cons in each of the chosen sources both source two and three were meta analyses thus both having an extensive

List of reliable sources having the overall report much more reliable be much more reliable the reliability of the first source can be questioned as a sample size of 50 can be considered too small to produce results that comprehensively support the aim all three sources were acquired by renowned scientific sources thus making them fairly reliable overall although

Source 1 and 2 show a clear correlation between methylphenidate usage and adhd adhd symptom reduction source 3 counters this by showing results that support the argument that mesophanate is not effective in treatment in all patients in conclusion although sources 1 and 2 show a clear correlation between methylphenidate usage and adhd symptom reduction along with

The improvement in working memory and thus making it a good treatment for children diagnosed with adhd it can also be debated that methylphenidate is not a miracle drug for the disorder and will not work on all individuals thank you
