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.

New world-class Chemistry facilities at UFS
2011-11-22

 

A world-class research centre was introduced on Friday 18 November 2011 when the new Chemistry building on the Bloemfontein Campus of the University of the Free State (UFS) was officially opened.
The upgrading of the building, which has taken place over a period of five years, is the UFS’s largest single financial investment in a long time. The building itself has been renovated at a cost of R60 million and, together with the new equipment acquired, the total investment exceeds R110 million. The university has provided the major part of this, with valuable contributions from Sasol and the South African Research Foundation (NRF), which each contributed more than R20 million for different facets and projects.
The senior management of Sasol, NECSA (The South African Nuclear Energy Corporation), PETLabs Pharmaceuticals, and visitors from Sweden attended the opening.

Prof. Andreas Roodt, Head of the Department of Chemistry, states the department’s specialist research areas includes X-ray crystallography, electrochemistry, synthesis of new molecules, the development of new methods to determine rare elements, water purification, as well as the measurement of energy and temperatures responsible for phase changes in molecules, the development of agents to detect cancer and other defects in the body, and many more.

“We have top expertise in various fields, with some of the best equipment and currently competing with the best laboratories in the world. We have collaborative agreements with more than twenty national and international chemistry research groups of note.

“Currently we are providing inputs about technical aspects of the acid mine water in Johannesburg and vicinity, as well as the fracking in the Karoo in order to release shale gas.”

New equipment installed during the upgrading action comprises:

  • X-ray diffractometers (R5 million) for crystal research. Crystals with unknown compounds are researched on an X-ray diffractometer, which determines the distances in angstroms (1 angstrom is a ten-billionth of a metre) and corners between atoms, as well as the arrangement of the atoms in the crystal, and the precise composition of the molecules in the crystal.
  • Differential scanning calorimeter (DSC) for thermographic analyses (R4 million). Heat transfer and the accompanying changes, as in volcanoes, and catalytic reactions for new motor petrol are researched. Temperature changes, coupled with the phase switchover of fluid crystals (liquid crystals -watches, TV screens) of solid matter to fluids, are measured.
  • Nuclear-magnetic resonance (NMR: Bruker 600 MHz; R12 million, one of the most advanced systems in Africa). A NMR apparatus is closely linked with the apparatus for magnetic resonance imaging, which is commonly used in hospitals. NMR is also used to determine the structure of unknown compounds, as well as the purity of the sample. Important structural characteristics of molecules can also be identified, which is extremely important if this molecule is to be used as medication, as well as to predict any possible side effects of it.
  • High-performance Computing Centre (HPC, R5 million). The UFS’ HPC consists of approximately 900 computer cores (equal to 900 ordinary personal computers) encapsulated in one compact system handling calculations at a billion-datapoint level It is used to calculate the geometry and spatial arrangements, energy and characteristics of molecules. The bigger the molecule that is worked with, the more powerful the computers must be doing the calculations. Computing chemistry is particularly useful to calculate molecular characteristics in the absence of X-ray crystallographic or other structural information. Some reactions are so quick that the intermediary products cannot be characterised and computing chemistry is of invaluable value in that case.
  • Catalytic and high-pressure equipment (R6 million; some of the most advanced equipment in the world). The pressures reached (in comparison with those in car tyres) are in gases (100 times bigger) and in fluids (1 500 times) in order to study very special reactions. The research is undertaken, some of which are in collaboration with Sasol, to develop new petrol and petrol additives and add value to local chemicals.
  • Reaction speed equipment (Kinetics: R5 million; some of the most advanced equipment in the world). The tempo and reactions can be studied in the ultraviolet, visible and infrared area at millisecond level; if combined with the NMR, up to a microsecond level (one millionth of a second.

Typical reactions are, for example, the human respiratory system, the absorption of agents in the brain, decomposition of nanomaterials and protein, acid and basis polymerisation reactions (shaping of water-bottle plastic) and many more.
