BACKGROUND A cardiac syndrome of "apical ballooning" was recently described, consisting of an acute onset of transient extensive akinesia of the apical and mid portions of the left ventricle, without significant stenosis on the coronary angiogram, accompanied by chest symptoms, ECG changes, and a limited release of cardiac markers disproportionate to the extent of akinesia. Until now, this synd...

In a review of the electroencephalographs (E.E.G.) in patients suffering from Parkinson's syndrome, England and his colleagues (England, Schwab, and Peterson, 1959) reported the association of E.E.G. slow wave abnormalities with those severe forms of the disease which showed, in addition to tremorrigidity symptoms, mental changes and akinesia. They defined akinesia as 'a reduction or loss of ab...

BACKGROUND Sub-Tenon's anaesthetic is effective and reliable in producing both akinesia and anaesthesia for cataract surgery. Our clinical experience indicates that it is sometimes necessary when absolute akinesia is required during surgery to augment the block with 1-2 ml of local anaesthetic. Hypothesis was that after first injection some of the volume injected may spill out and before second...

Primary motor cortex (MI) neurons discharge vigorously during voluntary movement. A cardinal symptom of Parkinson's disease (PD) is poverty of movement (akinesia). Current models of PD thus hypothesize that increased inhibitory pallidal output reduces firing rates in frontal cortex, including MI, resulting in akinesia and muscle rigidity. We recorded the simultaneous spontaneous discharge of se...

Rigor, tremor, akinesia: The classic triad of symptoms of Parkinson's disease,which you can probably recite in your sleep. However, a tremor is also a symptom of several other disorders that are relevant in clinical practice. In the following article we discuss the most important differential diagnosis of tremor. By studying the many examples and tips in this article you will be perfectly prepa...

The epoxy fatty acid cis-12,13-epoxy-oleic acid, which acts as a DNA adduct, may be generated during long-term storage of many seed oils, including those used in cooking, with frying oils and fried foods being a major source in the modern human diet. Removal of this epoxy fatty acid from the locus of the N-formyl peptide receptors was associated with recovery from cogwheel rigidity and akinesia...

A study of movement disorders such as Parkinson's disease and Huntington's disease can provide an indication of the motor functions of the basal ganglia. Basal-ganglia diseases affect voluntary movement and can cause involuntary movement. Deficits are often manifested during the coordination of fine multi-joint movements (e.g., handwriting). The disturbances of motor control (e.g. akinesia, bra...

A 28 year old woman with the Prader-Willi syndrome developed chest pain and loss of anterior R wave amplitude on the electrocardiogram. Cardiac catheterization demonstrated a severe proximal stenosis of the left anterior descending artery with delayed antegrade flow together with antero-apical akinesia consistent with myocardial infarction. Physicians involved in the management of patients with...
