My present stand on DBS in India

If I receive a mail enquiry from someone I do not know, I give them a list of places where DBS is done. If someone I know asks, I tell them pros and cons and give a list mentioning where the largest numbers are from. I specifically mention the purely symptomatic nature of therapy, the requirement for intensive follow up and the problems of DBS/ dopaminergic dose reduction on cognition and behavior. However if it is a relative who asks, I would not recommend DBS if they have to sell land or leave their job and relocate. I tell them that optimal medical and physical therapy is still very much an option; that most available literature recommending DBS is of short duration (6 to 24 months) or inadequate numbers if longer duration, implying that the long term benefits are being extrapolated. (I don't mention conflict of interest due to involvement of the company manufacturing the device.)

Electrical injury and non progressive motor syndromes

Electrical injury and amyotrophic lateral sclerosis: a systematic review of the literature.

Abhinav K, Al-Chalabi A, Hortobagyi T, Leigh PN.

Queen Elizabeth Hospital, London, UK.

Electrical injury may act as a potential precipitating or risk factor for amyotrophic lateral sclerosis (ALS). A systematic review of the literature was undertaken to assess the relationship between electrical injury and the development of ALS. Information for the review was obtained using five medical databases, and from manual searching of individual papers. Patients presenting with a neurological syndrome after electrical injury, including lightning, were included and classified into four categories: ALS; progressive upper motor neurone (UMN) syndrome; progressive lower motor neurone (LMN) syndrome; and non-progressive syndrome. Linear regression and chi2 testing were used for analysis of the data. 96 individuals, comprising 44 with ALS, 1 with a progressive UMN syndrome, 7 with a progressive LMN syndrome and 44 with a non-progressive syndrome, were identified from 31 papers with publication dates between 1906 and 2002. The median interval between electrical injury and disease onset was 2.25 years for all progressive syndromes and just over 1 week for the non-progressive syndrome. The more severe the shock (excluding lightning), the

more likely individuals were to have a non-progressive motor syndrome. A non-progressive spinal cord syndrome is associated with more severe electrical injury. Overall, the evidence reviewed does not support a causal relationship between ALS and electric shock.

Neurology and Psychiatry

C Butler, A Z J Zeman. Neurological syndromes which can be mistaken for psychiatric conditions. J Neurol Neurosurg Psychiatry 2005;76:i31-i38.

All illness has both psychological and physical dimensions. This may seem a startling claim, but on reflection it is uncontroversial. Diseases don’t come to doctors, patients do—and the processes by which patients detect, describe, and ponder their symptoms are all eminently psychological. This theoretical point has practical implications. If we adopt a “bio-psycho-social” approach to illness generally, one which recognises the biological, psychological, and social aspects of our lives, we become less likely to neglect the treatable psychological origins of many physical complaints (from globus hystericus to full blown conversion disorder) and the treatable psychological consequences (such as depression and anxiety) of much physical disease.

Abstract
Neuromyelitis optica (NMO) is an inflammatory demyelinating disease of the central nervous system characterized by optic neuritis and longitudinal extensive transverse myelitis. The clinical course can be either polyphasic (relapsing-remitting) or monophasic. The relapsing-remitting course is observed in more than 80% of NMO cases, and relapse generally occurs within 1 year in 60% of patients, and within 3 years in 90%. We report a rare case of long spontaneous remission in untreated NMO.

Spontaneous recovery in ADEM?

INFLAMMATORY/POST-INFECTIOUS ENCEPHALOMYELITIS

L Bennetto, N Scolding

Spontaneous recovery is the rule, usually over a course of weeks to months. ADEM tends to have a more severe initial course but much better ultimate recovery than MS. Historically fatal disease was common, with reported mortality rates as high as 30–50% as recently as 1948 in European children with post-vaccination ADEM. The outlook this millennium appears much brighter, with three recent studies encompassing 150 children with ADEM reporting no deaths. One of these studies followed up their 35 cases for a mean 5.8 years and found that the majority completely recovered in a few weeks. Twenty patients had no long term impairment; permanent neurological deficits included motor dysfunction (six patients, severe in three), cognitive impairment (four patients), visual loss (four patients), and behavioural problems (four patients). Epilepsy developed in three patients but persisted in only one with extended follow up. A recent study of 40 adult patients with ADEM reported two mortalities, suggesting that adult ADEM may presently have a slightly worse prognosis than childhood ADEM.

Treatment options

Corticosteroids are widely considered to be an effective first line treatment for ADEM. Intravenous methylprednisolone 1 g daily for at least three days is advised. While expert opinion and several convincing reports support this regimen, the natural history of ADEM of course features spontaneous improvement, and it is difficult therefore to be absolutely certain of its benefits. The recent trend towards improved survival in reported case series of ADEM may, however, reflect increased use of corticosteroids, intravenous methylprednisolone in particular. The rationale for corticosteroid use is their ability to reduce inflammation, decrease oedema, and seal the blood–brain barrier, which should decrease the further influx of active immune cells and humoral factors, contributing to demyelination. In some cases, cessation of steroid treatment has been followed by a relapse, possibly forming the basis of MDEM. As a relapse suggestive of MDEM is most likely shortly after ADEM it would seem prudent to prescribe a 1–2 month oral prednisolone taper.

Plasma exchange is recommended in patients who respond poorly to intravenous corticosteroids. There have also been several reports of impressive responses to plasma exchange; however, some of these have been confounded by the co-administration of corticosteroids and cyclophosphamide. More importantly a randomised, controlled, crossover trial of true versus sham plasma exchange for attacks of severe CNS demyelination resistant to corticosteroid treatment in 22 patients showed that 42% of patients had moderate or greater neurological improvement in the plasma exchange arm compared with just 6% of the patients receiving sham treatment (statistically significant). Although this study only had one patient with ADEM, the other conditions treated under the remit of “severe CNS demyelination”—MS, Marburg variant MS, acute transverse myelitis, neuromyelitis optica—are sufficiently similar and occasionally indistinguishable from ADEM in the acute phase to represent a reasonable rationale for treatment at present. This study used a course of seven plasma exchanges over 14 days, but improvement is frequently observed after the first exchange.

Intravenous immunoglobulin (IVIG) has also been used with success in a few cases of ADEM. While the evidence behind its use in ADEM is probably weaker than that of plasma exchange, there are several neuro-inflammatory conditions where IVIG has a proven effect and is often considered a more convenient alternative to plasma exchange. At present it should be reserved for ADEM that fails to respond to corticosteroid treatment and where plasma exchange is contraindicated or impractical. There have been suggestions based on subtle pathogenetic differences that IVIG may be preferable to plasma exchange in cases of post-vaccination encephalomyelitis, but this is not proven. Intravenous cyclophosphamide has also been used in the past with some apparent success but has not gained widespread recommendation.

In severe cases of ADEM, and particularly acute haemorrhagic leucoencephalomyelitis, cerebral oedema can occur and should be treated with combinations of mannitol and hyperventilation. If these conservative measures fail then more drastic measures such as craniotomy can be considered.

ADEM has been known to relapse into MDEM following routine vaccinations and it would seem sensible to avoid vaccinations (or other immune stimulation) for at least six months following a diagnosis of ADEM.

The groom who could not say “I do”

A 25-year-old North American man came to Portugal on honeymoon. The week before, he had developed slowly progressive difficulty with both speaking and swallowing. At his wedding ceremony in the USA 2 days earlier, he had not been able to speak, saying “I do” using gestures, and could barely eat his own wedding cake. He deteriorated further after the wedding and by the following day he was unable to swallow.

Ten days before the onset of these symptoms, he had suffered a flu-like illness that resolved spontaneously over a couple of days. He was previously healthy, not taking any medication and not using any illicit drugs.

On examination, he was calm and alert, capable of following commands and could read and write which facilitated communication. He was anarthric, making only effortful guttural sounds and required nasogastric tube feeding because of severe dysphagia. He had bilateral ptosis and bilateral facial weakness. However, while his voluntary mouth opening was limited, it was normal when he yawned. His palatal movement was reduced but his gag reflex was intact, as was his jaw jerk. He could not cough voluntarily but had a reflex cough. He was unable to protrude or move his tongue from side to side. Ocular movements were normal and he had normal strength in his arms and legs with symmetrical tendon reflexes. He was apyrexial and haemodynamically stable. The rest of his general examination was normal.

Abstract

The overlap of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) has been well documented in FTD patients with co-morbid motor neuron degeneration and in ALS patients with frontotemporal dysfunction. Up to 15% of FTD patients and 30% of ALS patients experience the overlap syndrome. The syndrome may be difficult to identify since patients often present either to a neuromuscular clinic or a memory disorder's center, each which may have limited expertise in the other specialty. Survival is greatly impacted for both disorders in the co-morbid condition, making identification of this syndrome critical. The clinical characteristics of the overlap syndrome with new diagnostic criteria will be discussed along with screening strategies, including the UCSF Screening battery and clinical neurophysiology techniques. Treatable mimics of this disorder will also be described and management techniques. Neuroimaging findings will be summarized, which show that the frontotemporal impairment in ALS patients lies on a continuum. Identification of the overlap syndrome also provides a unique opportunity to study very early signs of FTD and conversely, very early signs of ALS, to gain greater insight into both disorders.

Questions on EEG

1. What is electricity?
2. How do we measure it? 
3. What do we measure when we put an electrode on the scalp?
4. Obviously there is no movement of electrons across the electrodes, so it must be measuring some sort of a field. What is meant by electric field, how is it different from electromagnetic field and electrostatic field?

Structure of matter

Not only do electrostatic occurrences permeate the events of everyday life, without the forces associated with static electricity, life as we know it would be impossible. Electrostatic forces - both attractive and repulsive in nature - hold the world of atoms and molecules together in perfect balance. Without this electric force, material things would not exist. Atoms as the building blocks of matter depend upon these forces. And material objects, including us Earthlings, are made of atoms and the acts of standing and walking, touching and feeling, smelling and tasting, and even thinking is the result of electrical phenomenon. Electrostatic forces are foundational to our existence.

Boyle's studies (middle to late 1600s) of gaseous substances promoted the idea that there were different types of atoms known as elements. Dalton (early 1800s) conducted a variety of experiments to show that different elements can combine in fixed ratios of masses to form compounds. Dalton subsequently proposed one of the first theories of atomic behavior that was supported by actual experimental evidence.

English scientist J.J. Thomson's cathode ray experiments (end of the 19th century) led to the discovery of the negatively charged electron and the first ideas of the structure of these indivisible atoms. Thomson proposed the Plum Pudding Model, suggesting that an atom's structure resembles the favorite English dessert - plum pudding. The raisins dispersed amidst the plum pudding are analogous to negatively charged electrons immersed in a sea of positive charge.

Nearly a decade after Thomson, Ernest Rutherford's famous gold foil experiments led to the nuclear model of atomic structure. Rutherford's model suggested that the atom consisted of a densely packed core of positive charge known as the nucleus surrounded by negatively charged electrons. While the nucleus was unique to the Rutherford atom, even more surprising was the proposal that an atom consisted mostly of empty space. Most the mass was packed into the nucleus that was abnormally small compared to the actual size of the atom.

Neils Bohr improved upon Rutherford's nuclear model (1913) by explaining that the electrons were present in orbits outside the nucleus. The electrons were confined to specific orbits of fixed radius, each characterized by their own discrete levels of energy. While electrons could be forced from one orbit to another orbit, it could never occupy the space between orbits.

Bohr's view of quantized energy levels was the precursor to modern quantum mechanical views of the atoms. The mathematical nature of quantum mechanics prohibits a discussion of its details and restricts us to a brief conceptual description of its features. Quantum mechanics suggests that an atom is composed of a variety of subatomic particles. The three main subatomic particles are the proton, electron and neutron. The proton and neutron are the most massive of the three subatomic particles; they are located in the nucleus of the atom, forming the dense core of the atom. The proton is charged positively. The neutron does not possess a charge and is said to be neutral. The protons and neutrons are bound tightly together within the nucleus of the atom. Outside the nucleus are concentric spherical regions of space known as electron shells. The shells are the home of the negatively charged electrons. Each shell is characterized by a distinct energy level. Outer shells have higher energy levels and are characterized as being lower in stability. Electrons in higher energy shells can move down to lower energy shells; this movement is accompanied by the release of energy. Similarly, electrons in lower energy shells can be induced to move to the higher energy outer shells by the addition of energy to the atom. If provided sufficient energy, an electron can be removed from an atom and be freed from its attraction to the nucleus.

Summary:

• All material objects are composed of atoms. There are different kinds of atoms known as elements; these elements can combine to form compounds. Different compounds have distinctly different properties. Material objects are composed of atoms and molecules of these elements and compounds, thus providing different materials with different electrical properties.
• An atom consists of a nucleus and a vast region of space outside the nucleus. Electrons are present in the region of space outside the nucleus. They are negatively charged and weakly bound to the atom. Electrons are often removed from and added to an atom by normal everyday occurrences. These occurrences are the focus of this Static Electricity unit.
• The nucleus of the atom contains positively charged protons and neutral neutrons. These protons and neutrons are not removable or perturbable by usual everyday methods. It would require some form of high-energy nuclear occurrence to disturb the nucleus and subsequently dislodge its positively charged protons. These high-energy occurrences are fortunately not an everyday event. One sure truth of this unit is that the protons and neutrons will remain within the nucleus of the atom. Electrostatic phenomenon can never be explained by the movement of protons.

Concepts in Static Electricity

Rubbing two objects against each other brings the electron fields of the atoms in each close to each other. Electron affinity varies amongst molecules. If there is a significant difference in this property between the two objects being rubbed against each other, then electrons will be transferred. This will result in a charge on the surface of both objects. The charge will obviously be of opposite polarity. It will also be equal in magnitude. This is known as the "Law of conservation of charge". A triboelectric series is the order in which objects are arranged according to the degree of electron affinity.

From the literature and our experience, a relatively consistent picture of psychiatric and behavioral abnormalities in Wilson's disease emerges. The essential elements of this picture are as follows: 

1. Psychiatric and behavioral abnormalities are frequent manifestations of WD. The estimates range from 30% (18) to 100% (2) of symptomatic patients. As Wilson himself was the first to state in reference to "mental change," "its importance should not be underestimated." 

2. Psychiatric and behavioral abnormalities are often the initial manifestations of WD. Two thirds of our patients first presented with psychiatric symptoms and one third received psychiatric treatment before the diagnosis of WD was made. In the early stages of the disease, when psychiatric and behavioral symptoms predominate, the diagnosis is often missed. Of our 124 patients, WD was diagnosed in only one during this phase. Until the psychiatric presentation of WD is recognized, and the disease is included in the differential diagnosis of psychiatric symptoms, its diagnosis will be missed or delayed. In our patients, and others' (13,15), the delay in diagnosis ranged from 1 to 5 years. Such a delay is particularly tragic as favorable outcome depends upon early discovery. 

3. The most common of the psychiatric and behavioral manifestations of WD include: personality changes such as irritability and low threshold to anger, depression sometimes leading to suicidal ideation and attempts, deteriorating academic and work performance that is present in almost all neurologically affected patients. We (1) have also observed, as did Scheinberg and Sternlieb (2) that WD patients exhibit increased sexual preoccupation and reduced sexual inhibition. Finally, cognitive impairment, psychosis, anxiety, and other psychiatric disorders, although less frequent, also occur. 

4. Some of the psychiatric and behavioral symptoms are reversible with WD-specific therapy, whereas others are not. We are impressed with the frequency with which the behavioral and "cognitive" symptoms are reversed over 1 to 2 years of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Retinal Vasculitis with CNS disease

In a patient with retinal vasculitis, it is useful to know the following:
1) Type of retinal vessels involved - arterioles, venules, capillaries
2) CSF study normal or abnormal
3) MRI Brain normal, vasculitis, white matter changes, ventricular enlargement

Identification of retinal vessels involved

Retinal vasculitis affecting predominantly the veins (phlebitis) has been described in association with Behçet's disease, tuberculosis, sarcoidosis, multiple sclerosis, pars planitis, retinal vasculitis associated with tuberculoprotein hypersensitivity (Eales' disease), human immunodeficiency virus infection (HIV). Retinal arteritis is more commonly seen in acute retinal necrosis, idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) and systemic vasculitides such as SLE, polyarteritis nodosa, and Wegener's granulomatosis, Churg-Strauss syndrome and cryoglobulinemia.
