According to Dr Munita Dunn-Coetzee, it is increasingly recognised that females with ADHD portray a different ‘picture’ in terms of behaviour, symptoms, and comorbidities when compared to males with ADHD.

I’m a failure as an adult. I’m a disappointment as a colleague. I’m a lousy friend. I’m a burden as a wife. I’m a bad mom and I’m constantly scrambling to try and hide it.

This is the secret interior reality of a group of neurodivergent adults who have been long overlooked by scientists and doctors alike. The Lost Generation. It is now recognised that there is an entire generation of women out there who have battled with ADHD (attention-deficit hyperactivity disorder) their entire lives – and don’t know it.

Women and girls living with ADHD

For decades, ADHD has been predominantly associated with hyperactive young boys bouncing off the walls. The reason for this widely-held misconception is due to the fact that studies originally focused on young European American boys – their symptoms becoming the benchmark for all. Women were not even included in ADHD studies until the late 1990s, and the first long-term study on girls was only conducted in 2002. The results? Girls’ ADHD symptoms bear little resemblance to those of boys. Dr Munita Dunn-Coetzee, Director of Student Counselling and Development at the UFS, agrees. “It is increasingly recognised that females with ADHD portray a different ‘picture’ in terms of behaviour, symptoms, and comorbidities when compared to males with ADHD. Females are less likely to be identified and referred for assessment, and their needs are less likely to be met.” Therefore, the majority of girls and women with ADHD remain un- or misdiagnosed.

But what does ADHD in women look like? First, let’s take a step back. There are three types of ADHD: the hyperactive type, the inattentive type, and the combined type – which includes both hyperactivity and inattention. Hyperactivity in females is much more likely to present internally, in the mind, and inattentiveness as daydreaming and disorganisation. This is much more than sitting still in class or having trouble with homework. Faced with behavioural and social pressures to perform, girls often learn to mask and overcompensate for their problems – making diagnosis even more difficult.

Carry the struggle to adulthood

When left untreated, girls with ADHD will most likely carry their struggle into adulthood. ADHD in adult women often results in chronic low self-esteem, self-loathing, feelings of inadequacy, sleeplessness, anxiety, depression, substance abuse, and eating disorders. Women with ADHD also typically present with tremendous time management challenges, chronic overwhelm, and exhaustion – exacerbated by societal pressures. The risk of self-harm and suicide attempts is also startlingly higher compared to their male counterparts.

There is tremendous hope, though. Drs Edward Hallowell and John Ratey – experts in the field who both have ADHD – describe ADHD as an array of traits specific to a unique kind of mind that can become a distinct advantage with appropriate treatment and support. ADHD is not a condemnation of character. Instead, it unveils a kaleidoscope of strengths and a unique constellation of traits deserving of celebration.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
