We compared the performance of 40 patients with frontal lobe dementia to that of 40 patients with subcortical vascular dementia (80 patients including, 46 men and 34 women) in a set of tasks assessing attentional, executive, and behavioural tasks. The frontal lobe dementia represents an important cause for degenerative disruption and is increasingly recognised as an important form (up to 25%) of degenerative dementia among individuals of late-middle-age. The main involvement is the frontal-subcortical pathway, which is the final target of impairment even in subcortical vascular dementia.

Nevertheless, its clinical role in the detection of early dementia and its correlations with other cognitive processes is still under investigation. Vascular dementia is an uncertain nosological entity, in which unevenly distributed patterns of cognitive deficits comprising slowing of cognitive processing and impairment of executive function occur.

Brain injury by therapeutic irradiation has traditionally been classified according to its time of onset into acute, early delayed, and late forms.

Patients And Methods: Study subjects were men and women 60-75 years of age diagnosed with probable FTD. The rivastigmine group received doses of 3-9 mg/day.
In cross-sectional studies, low levels of folate and B12 have been shown to be associated with cognitive decline and dementia Evidence for the putative role of folate, vitamin B12 in neurocognitive and other neurological functions comes from reported cases of severe vitamin deficiencies, particularly pernicious anemia, and homozygous defects in genes that encode for enzymes of one-carbon metabolism. The neurological alterations seen in these cases allow for a biological role of vitamins in neurophysiology. Results are quite controversial and there is an open debate in literature, considering that the potential and differential role of folate and B12 vitamin in memory acquisition and cognitive development is not completely understood or accepted.

Subcortical VaD is characterised by executive dysfunction and behavioural problems, reflecting deterioration of the frontal lobe. Based on limited open-labelled controlled studies of rivastigmine in VaD, this article aims to determine whether rivastigmine, a dual inhibitor of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), has any effects on the typical symptoms of subcortical VaD.

Disabilities caused by behavioral problems can be potentially devastating in cognitively impaired patients. These behavioral symptoms can be a major cause of stress, anxiety, and concern for caregivers. While psychotropic drugs are frequently used to control these symptoms, they can be accompanied by significant side effects, which include sedation, disinhibition, depression, falls, incontinence, parkinsonism, and akathisias.

Chronic hiccup is not so rare in patients suffering from stroke: its impact on quality of life and on rehabilitation management is substantial, and it may be closely related to aspiration pneumonia, respiratory arrest and nutritional depletion.
Review Summary: Intractable hiccups can be associated with potentially fatal consequences and safe management may require inpatient rehabilitation.
Background: Although the core feature of dementia is progressive cognitive disruption, non-cognitive behavioural problems are expressed in most patients with dementia during the course of their illness. While psychotropic drugs are frequently used to control behavioural symptoms, comorbidities, which are very common in the geriatric population, could often limit their use. Gabapentin may be a potential treatment in such situations.

However, there is still open debate on the possible consequences of chronic subthalamic stimulation on general cognitive performance. A general amelioration of cognitive performance, in particular of executive functions has been reported but results are not homogeneous.

Subcortical vascular dementia (VaD) is characterized by executive dysfunction and behavioral problems, reflecting deterioration of the frontal lobe. This study aimed to determine whether rivastigmine, a dual inhibitor of acetylcholinesterase (AChE) and butyryl-cholinesterase (BuChE), has any effects on the typical symptoms of subcortical VaD. Patients receiving rivastigmine showed a slight improvement in executive functions and in behavior.

These noncognitive problems lead to potentially devastating disabilities, and are often a major cause of stress, anxiety and concern for caregivers. Psychotropic drugs are frequently used to control these symptoms, but they have the potential for significant side effects, such as sedation, disinhibition, depression, falls, incontinence, parkinsonisms and akathisias.

Alzheimer's disease is the most frequent form of dementia, where behavioral and cognitive disruption symptoms coexist. Depression, apathy, anxiety, and other conduct disorders are the complaints most often reported by caregivers. Fifty subjects were referred to our Institute with a diagnosis of probable Alzheimer's disease.

The serotoninergic system is tightly bound to frontal circuits, whose degeneration subserves FTD. Patients aged 64-68 years, with a diagnosis of FTD, were randomized to receive paroxetine up to 20 mg/day (n = 8) or piracetam up to 1,200 mg/day (n = 8).

Deep brain stimulation of the subthalamic nucleus has been recognized as one of the most promising techniques to decrease "off" motor symptoms and motor fluctuations, allowing a reduction of drug therapy and limiting side effects of the drugs. There is still open debate on the possible consequences of chronic subthalamic stimulation in other ways, apart from motor symptoms, of general cognitive performance.

Patients aged 65-80, with a diagnosis of dementia and probable VaD, received rivastigmine 3-6 mg/day (n=8) or cardioaspirin (n=8) in an open study for 22 months. At 22 months, patients treated with rivastigmine showed significant improvements in executive function and behavioural symptoms (both p<0.

Since the parietal area is one of the areas most involved in this degenerative pathology, we focused on the possible role of the parietal lobe, in learning and executing simple and complex motor sequences. We also attempted to describe the role of the parietal area in spatial and visual control, which is necessary to define and optimise movement execution in daily living.

There are different pharmacological therapies which are tried to treat the neuralgia: carbamazepin, phenytoin, diazepam, amytriptyline, phenobarbital, ketamine, and baclofen; there are also surgical treatment proposed in order to cure the neuralgia such as vascular decompression or electrical stimulation of the motor cortex controlateral to the pain area. We report a single case of a patient with glossopharyngeal neuralgia treated with Gabapentin, the first described, who was followed up for four years, who respond completely to the therapy and did not complain from side effects, reducing even the reminiscence of pain during the second cluster of crisis.

Objectives: The purpose of this study was twofold: to explore possible employment of the Ten-Point Clock Test in early identification of different types of cognitive distribution and to relate to its execution to other specific impairment, bound to the selected pathology.
Method: We compared 30 patients with FLD, to a group of 30 probable-AD patients accordingly to the NINCDS-ADRDA criteria, and to a group of 30 probable VaD patients, according to the NINDS-AIREN criteria.
