Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias


In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

[Mentalizing deficit in neurological disorders: a review article]

[Introduction – Mentalization is the ability to attribute mental states (intentions, desires, thoughts, emotions) to others, and hence to predict their behaviour. This ability fundamentally determines our participation in social relationships and adaptation to society. A significant proportion of the disorders of the central nervous system (CNS) affects those brain structures and neurotransmitter systems that play a role in the mentalizing processes. Accordingly, a number of CNS disorders may be associated with mentalizing deficits, which may affect the outcome of these diseases. Here, we review recent research on mentalizing abilities in neurological diseases. Methods – An internet database search was performed to identify publications on the subject. Results – Sixty-two publications in English corresponded to the search criteria. These publications reported impaired mentalization in several neurological disorders (e.g. epilepsy, Parkinson’s disease, multiple sclerosis, dementias, traumatic brain injury). Discussion – The results indicate that a number of neurological disorders associate with mentalizing deficit. This deficit is often present in the early stages of the diseases and has a prognostic value, which in turn emphasizes the importance of the early detection and adequate rehabilitation.]

[Frontotemporal dementia - Part II Differential diagnosis, genetics, molecular pathomechanism and pathology]

GALARIOTIS Vasilis, BÓDI Nikoletta, JANKA Zoltán, KÁLMÁN János

[This is a comprehensive paper in three parts covering history, prevalence, clinical forms, differential diagnosis, genetics, molecular pathomechanism, pathology, clinical diagnosis and treatment of frontotemporal dementia (FTD). The second part focuses on the differential diagnosis, genetics, molecular pathomechanism and pathology. The clinical diagnosis of frontotemporal dementia is based on the presence of a prominent disturbance of the executive function and of frontal lobe syndrome or a progressive aphasic syndrome without severe global cognitive impairment. Of other dementias, it is primarily Alzheimer’s disease that it should be differentiated from, but other psychiatric disorders must also be ruled out. The disease has familial and sporadic forms. Recent identification of mutations in the gene encoding the microtubule-associated tau protein in the inherited frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) has demonstrated that various tau dysfunctions can lead to neurodegeneration. Tau gene mutations have varied effects on the biology and function of the protein. This heterogeneous pathomechanism explains the wide range of clinical and neuropathological features observed in the FTDP-17. Tau and ubiquitin antibodies can be detected by sensitive immunohistochemical methods. The diagnosis of FTD should be based on neuropathological examination, and this is also the only method by which it can be definitely differentiated from other types of dementias.]

[Frontotemporal dementia - Part I History, prevalence, clinical forms]

GALARIOTIS Vasilis, BÓDI Nikoletta, JANKA Zoltán, KÁLMÁN János

[The authors report a comprehensive publication consisting of three parts going into the details of history, prevalence, clinical forms, differential diagnosis, genetics, molecular pathomechanism, pathology, clinical diagnosis and treatment of frontotemporal dementia (FTD). The first part of the present review deals with history, prevalence and clinical forms of FTD. The prototypical FTD with circumscribed atrophy was first described by Arnold Pick; Alois Alzheimer found the intraneural inclusions in the patients’ brain. Later it was recognised that many patients had neither the atrophy nor the cellular changes, but genetic mutations have been identified. Frontotemporal dementia is a degenerative condition with unknown etiology in the frontal and anterior temporal lobes of the brain. It is a progressive neurobehavioral syndrome characterized by early decline in social interpersonal conduct, early impairment in the regulation of personal conduct, early emotional blunting, and early loss of insight. There are no reliable epidemiological studies on the prevalence of FTD, but it is well-accepted that FTD is a common cause for dementia before the age of 65 (it constitues approximately five percent of all irreversible dementias). The nomenclature of the FTD has been confusing and continues to be. Three major clinical syndromes can be identified: 1 frontal variant FTD (dementia of frontal type) in which changes in social behavior and personality predominate, 2. in semantic dementia (progressive fluent aphasia) there is a breakdown in the conceptual database which underlies language production and comprehension, 3. in progressive nonfluent aphasia the phonologic and syntactic components of language are affected. The authors report two cases, which can point to clinical symptoms and forms, and mention the problems of the differential diagnosis and therapy.]

[Report from the World Congress of Psychopharmacology in Florence]


[The 14th Congress of the Collegium Internationale Neuro-Psychopharmacologicum was held in Florence, Italy, from 19 to 23 June 1984. The main theme this time was depression. A special section dealt with the aetiological and pathogenetic aspects of Alzheimer's and senile-type dementias, especially as regards the specific receptor regulation of the brain. Several presentations were also given on the electrophysiological investigation of the relationship between the dopaminergic system and psychotropic drugs. The analgesic, anxiolytic, anticonvulsant, and anticonvulsant effects of beta-blockers on headache were the subject of a special symposium.]
