15 more creative and catchy neurology headlines for 2019

Regular visitors to this blog know that we love catchy article titles. It is always heartwarming to see how some authors create imaginative and inventive headlines. This skill involves the ability to play with words, and the capacity to be double-edged. This is why this blog keeps a lookout for fascinating neurology titles. And in line with this tradition, and in no particular order of inventiveness, here are 15 more catchy neurology titles!

15. Who do they think we are? Public perceptions of psychiatrists and psychologists

This paper, for some unfathomable reason, set out to ask if the public knows the difference between what psychiatrists and psychologists actually do. And the authors discovered that “there is a lack of clarity in the public mind about our roles”. More worryingly, or reassuringly (depending on your perspective), they also found out that “psychologists were perceived as friendlier and having a better rapport“. Not earth-shattering discoveries, but what a great title!

14. OCT as a window to the MS brain: the view becomes slightly clearer

Optical coherence tomography (OCT) is a cool tool which measures the thickness of the retinal fiber layer (RFL). And it has the habit of popping its head up in many neurological specialties. In this case, the specialty is multiple sclerosis, and the subject is how OCT influences its diagnosis and surveillance. Surely a window into the brain is easier to achieve than one into the soul.

13. A little man of some importance 

The homonculus is the grotesque representation of the body on the surface or cortex of the brain. This paper reviews how formidable neurosurgeons such as Wilder Penfield worked out the disproportionate dimensions of this diminutive but influential man. He (always a man for some reason) has giant hands, a super-sized mouth, very small legs, and a miniature trunk. The clever brain doesn’t readily allocate its resources to large body parts that perform no complex functions! But be warned, this article is no light-weight reading!

12. Brain-focussed ultrasound: what’s the “FUS” all about? 

This title is a play on words around MR-guided focussed ultrasound surgery (MRgFUS), an emerging technique for treating disorders such as essential tremor and Parkinson’s disease (PD). This review looks at the controversial fuss that this technique has evoked.

11. The Masks of Identities: Who’s Who? Delusional Misidentification Syndromes

This paper explores the interesting subject of delusional misidentification syndromes (DMSs). The authors argue that few concepts in psychiatry can be as confusing as DMSs. And they did an excellent job of clearing our befuddlement around delusions such as Capgras and Fregoli. Very apt title, very interesting read.

10. Waking up to sleeping sickness.

This title belongs to a review of trypanosomiasis, aka sleeping sickness. It is a superb play on words, one that evokes several levels of meaning. It is simple and yet complex at the same time. Great imagination.


09. Brains and Brawn: Toxoplasma Infections of the Central Nervous System and Skeletal Muscle

This paper discusses two parts of nervous system that are affected by toxoplasmosis. Playing on the symbolic  contradiction between intellect and strength, the authors show how toxoplasmosis is an ecumenical abuser: it metes out the same fate to both brain and brawn.

08. Shedding light on photophobia

A slightly paradoxical title this one. Ponder on it just a little more! And then explore the excellent paper shedding light on a condition that is averse to light.

07. No laughing matter: subacute degeneration of the spinal cord due to nitrous oxide inhalation

Nitrous oxide, or laughing gas, is now “the seventh most commonly used recreational drug”. But those who pop it do so oblivious of the risk of subacute combined degeneration. This damage to the upper spinal cord results from nitrous oxide-induced depletion of Vitamin B1 (thiamine). Not a laughing matter at all!

06. To scan or not to scan: DaT is the question

Dopamine transport (DaT) scan is a useful brain imaging tests that helps to support the diagnosis of Parkinson’s disease and other disorders which disrupt the dopamine pathways in the brain. It is particularly helpful in ruling out mimics of Parkinson’s disease such as essential tremor. When to request a DaT scan is however a tricky question in practice. This paper, with its Shakespearean twist, looks at the reliability of DaT scans.

05. TauBI or not TauBI: what was the question?

It should be no surprise if Shakespeare rears his head more than once in this blog post. Not when the wordsmith is such a veritable source of inspiration for those struggling to invent catchy titles. This paper looks at taupathy, a neurodegeneration as tragic as Hamlet. It particularly comments on an unusual taupathy, one induced by traumatic brain injury. Curious.

04. Mind the Brain: Stroke Risk in Young Adults With Coarctation of the Aorta

What better way to call attention to a serious complication than a catchy title like this one. This paper highlights the neurological complications of coarctation of the aorta, a serious congenital cardiovascular disease. And the key concerns here are the risks of stroke and cerebral aneurysms. Cardiologists, mind the brain!

03. Diabetes and Parkinson disease: a sweet spot?

This paper reviews the unexpected biochemical links between diabetes and Parkinson’s disease. And this relationship is assuming a rather large dimension. Why, for example, are there so many insulin receptors in the power house of Parkinson’s disease, the substantia nigra? A sweet curiosity.

02. PFO closure for secondary stroke prevention: is the discussion closed?

The foraman ovale is a physiological hole-in-the-heart which should close up once a baby is born. A patent foramen ovale (PFO) results when this hole refuses to shut up. PFOs enable leg clots to traverse the heart and cause strokes in the brain. This paper reviews the evidence that surgically closing PFOs prevents stroke. Common sense says it should, but science demands proof. And the authors assert that they have it all nicely tied up. Hmmm.

01. Closure of patent foramen ovale in “cryptogenic” stroke: Has the story come to an end?

Not to be beaten in the catchy title race is another brilliant PFO review article. Why do I feel the answer here is ‘no’? This is science after all.



The emerging research boosting Parkinson’s disease treatment

Parkinson’s disease (PD) is probably the most iconic neurological disorder. It has diverse manifestations, typical of many neurological diseases. PD is a result of brain dopamine deficiency, and its clinical picture is dominated by motor symptoms- tremor, rigidity and bradykinesia (slowing of movements). It however also manifests with a variety of non-motor symptoms which rival the motor symptoms in their impact. PD is responsive to treatment with several oral medications such as levodopa, infusions such as apomorphine, and interventions such as deep brain stimulation (DBS).


Regardless of the intervention used, PD is a neurodegenerative disorder that grinds, slowly and steadily, along a chronic progressive course. This often manifests with disabling features such as freezing, hallucinations, and dyskinesias (drug-induced writhing movements). These symptoms creep or barge in unannounced, challenging the wits of the neurologist, and pushing the resolve of patients and their families to the limit. What hope does research offer to smooth the journey for people with PD? Here are my top 7.

1. Increasing evidence for the benefit of exercise


OK, not every advance has to be groundbreaking. It is self-evident that exercise is beneficial for many chronic disorders, but proving this has been difficult…until now that is. Researchers, publishing in the journal Movement Disorders, looked at the benefits of exercise on cognitive function in PD, and their verdict is-yes, it works! The study, titled Exercise improves cognition in Parkinson’s disease: The PRET-PD randomized, clinical trial, comes with strings attached- you have to keep at the exercise for 2 years! A review  in the same journal indicates that exercise also improves mood and sleep in PD.

2. Lithium for treatment of dyskinesias

Dyskinesias are abnormal, fidgety movements that develop as side effects of the drugs used to treat PD. Most people with dyskinesias are not overly concerned about the movements because the alternative, disabling freezing and immobility, is worse. Dyskinesias are however energy-sapping, and are distressing for family members. Amantadine is one drug neurologists add-on to improve dyskinesias, but many people do not tolerate or benefit from this. The suggestion that lithium may help dyskinesias is therefore welcome news. The report comes from a study in mice reported in the journal Brain Research titled The combination of lithium and l-Dopa/Carbidopa reduces MPTP-induced abnormal involuntary movements (AIMs). A long way to go yet, but hope.

3. Transcranial magnetic stimulation (TMS)

Transcranial magnetic stimulation (TMS) is playing an increasing role in neurology as I discussed in a previous post titled Are magnets transforming neurology? It is almost inevitable therefore that TMS will crop up in attempts to treat PD. And so it has, going by a meta-analysis and systematic review published in JAMA Neurology. The paper is titled Effects of repetitive transcranial magnetic stimulation on motor symptoms in Parkinson disease. The reviewers passed the judgement that repetitive TMS improves motor symptoms in PD. Perhaps time to invest in TMS!

4. MRI guided focused ultrasound (MRgFUS)

MRI guided ultrasound (MRgFUS) is not new to medicine. It is used, for example, in the treatment of solid tumours and uterine fibroids. It is however innovative in the treatment of tremor and dyskinesia in PD. This came to my attention via a press release from University of Maryland titled Metabolic Imaging Center uses new ultrasound technology to target deep structures of the brain. MRgFUS non-invasively transmits ultrasound waves to the globus pallidus, one of the deep brain structures involved in PD. How this works still remains fuzzy to me, but it is exciting enough to generate a lot of research activity with articles such as MRI guided focused ultrasound thalamotomy for moderate-to-severe tremor in Parkinson’s disease in the journal Parkinson’s Disease; and Unilateral magnetic resonance-guided focused ultrasound pallidotomy for Parkinson disease, published in Neurology. Watch out, deep brain stimulation!

5. Nasal mucosal grafting

What a great thing, the blood-brain barrier, protecting the brain from all the bugs and toxins running amok in the bloodstream. This iron-clad fence unfortunately also effectively keeps out, or limits the entrance of, many beneficial drugs which need to get to the brain to act. As with all borders however, there are always people ready to break through, without leaving any tracks behind. And the people in this case are neurosurgeons who have successfully bypassed the blood brain barrier, and safely ‘transported’ PD drugs in to the brain. They did this by removing a portion of the blood brain barrier of mice, and replaced it with a piece of the tissue which lines the inside of the nose, a procedure called nasal mucosal grafting. They then delivered glial derived neurotrophic factor (GDNF), a protein that treats PD in mice, across the graft. The neurosurgeons explained all this in their paper titled Heterotopic mucosal grafting enables the delivery of therapeutic neuropeptides across the blood brain barrier. You may however prefer the simpler version from the Boston Business Journal (can you believe it!) titled A new way to treat Parkinson’s disease may be through your nose. It will however take time before human trials of nasal mucosal grafting…this is science after all, not science fiction!

6. Fetal stem cell transplantation

It doesn’t seem too long ago when all ethical hell broke loose because some scientists were transplanting fetal tissue into human brains. I thought the clamour had put this procedure into the locker, never to be resurrected. Apparently not; fetal stem cell transplantation (SCT) is back, reminiscent of Arnold Schwarzenegger in the Terminator films. Learn more of this comeback in this piece from New Scientist titled Fetal cells injected into a man’s brain to cure his Parkinson’s. The work is from Roger Barker‘s team at the University of Cambridge, and they are planning a big study into this named TRANSNEURO. Watch this space

7. Pluripotent stem cell transplantation

The future of stem cell transplantation probably lies with pluripotent, rather than fetal cells. The idea is to induce skin cells, called fibroblasts, to transform into dopamine-producing cells. Fibroblasts can do this because they are pluripotent cells; that is they are capable of becoming whatever type of cells you want, so long as you know the magic words. In this case, the words are likely to be the transcription factors Mash1, Nurr1 and Lmx1a. Beatsopen sesame‘, and surely less controversial than fetal cells. Researchers are taking this procedure very seriously indeed, setting out ground rules in articles such as Direct generation of functional dopaminergic neurons from mouse and human fibroblasts. This was published in the journal Nature, but you may prefer the easier read in New Scientist titled Brain cells made from skin could treat Parkinson’s. But don’t get too excited…pluripotent stem cell transplantation is barely at the starting line yet.

There is so much more going on in the field of Parkinson’s disease to cover in one blog post. I will review neuroprotection in Parkinson’s disease in a coming post. In the meantime, here are links to 12 interesting articles and reviews on the future of PD:
