There can be no criminal capability for an act unless the perpetrator had both the will to so act and the capacity to differentiate and choose whether or not to conform the particular behaviour to that dictated by the law. The capacity for choice must remain the fundamental issue. The range of conditions which can raise volition as a defence include: Somnambulism; post-traumatic syndromes; epilepsy; arteriosclerosis; or acts secondary to cerebral neoplasia. There is need to differentiate between reflex actions and automatisms and it is imperative that terms such as automatism or automatic behaviour are not perverted to allow an excuse for that which is inexcusable. Cases such as that of Cogdon, who was acquitted of murdering her daughter; Ramsbottom who was found guilty of causing a traffic accident despite having a stroke; Dennison in which a driver was found guilty despite epilepsy or Jenkins where the driver was initially found innocent of dangerous driving because of the unpredictable nature of diabetes are discussed. Special attention will be focused upon the case of Sullivan, a landmark in consideration of automatism in epilepsy. The paper examines insane verses non-insane automatism and the Australian legal system as it affects modern neurological practice. Suggestions are proffered as to how the law should be modified to better reflect justice as required within the context of modern medical knowledge.

Nine such patients were developmentally delayed, one was neurologically impaired and 16 were both developmentally delayed and neurologically impaired. A specific diagnosis of the non-ictal events was reached in 24 subjects-postures of spasticity in children with neurological impairment (6), Münchausen-by-proxy (5), pseudoseizures (3), breathholding (2), masturbation (2), reflux (2), shudder (1), movement disorder (1), motor tic (1) and pertussis (1). Specific descriptive patterns were assigned to the remaining 51 events. These included staring (20) and jerks (16) or unusual behaviour (15). 49 inter-event EEGs were normal; 7 displayed abnormal background rhythms and 19 showed epileptiform activity. We discourage use of the term 'pseudoseizure' for the majority of the events described and prefer that a specific diagnosis be made or a descriptive analysis be provided. The events seen illustrate the wide spectrum of childhood behaviour and on occasions suggest the need for telemetry to determine their true nature.</p>","PeriodicalId":75709,"journal":{"name":"Clinical and experimental neurology","volume":"29 ","pages":"92-8"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12517843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TCD had a sensitivity of 87%, a specificity of 80%, a positive predictive value of 93% and a negative predictive value of 67%. It was also able to give functional data when combined with arteriography and correctly identified the main pathology in 92% of those with abnormal TCD and angiogram. The 2 patients with false negative TCD had vertebral artery occlusion, which may be missed because of the signal from adjacent arteries. TCD may be a useful screening method in patients with VBI for the detection of large vessel occlusive disease of the intracranial vertebrobasilar system.

{"title":"XIXth century pre-Jacksonian concepts of epileptogenesis.","authors":"M J Eadie","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>By the beginning of the XIXth Century the old belief that epilepsy was due to demonic possession or to malevolent influences emanating from a variety of sources had largely given way to an acceptance that the disorder was a physical illness which arose in the brain, though in some not very precisely defined way. No even reasonably satisfactory hypotheses about epileptogenesis were available till Marshall Hall (1790-1857), from 1836 onwards, popularised the concept of reflex action which had earlier been described by Robert Whytt (1714-1776) under the name 'sympathy'. Marshall Hall interpreted epilepsy as due to abnormal irritability in the afferent limb or central section of what later came to be called the reflex arc, loss of consciousness in the seizures being the result of secondary cerebral venous congestion. This concept of epileptogenesis was refined by Brown-Séquard, who in 1858 ascribed a more important role to overt or occult peripheral afferent nerve irritability, considered that the central element of the relevant reflex mechanism involved the medulla oblongata, and believed that reflex cerebral vasospasm, rather than cerebral venous congestion, caused loss of consciousness in the seizures. Almost contemporaneously, Schroeder van der Kolk placed considerably greater emphasis on the medullary element in causing the increased excitability of the reflex arc that produced epileptic seizures. These ideas of exaggerated reflex activity as the mechanism of epilepsy were made redundant by the work of Hughlings Jackson (1837-1911), who from 1860 onwards demonstrated that epilepsy arose in the cerebrum itself, rather than from altered function at lower levels of the nervous system.</p>","PeriodicalId":75709,"journal":{"name":"Clinical and experimental neurology","volume":"29 ","pages":"26-31"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12517129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
