Abstract. We investigated theory of mind (ToM) deficits in Alzheimer‘s disease (AD) and its possible connection to autobiographical memory (ABM). Patients and matched controls were evaluated and compared using a video-based ToM test, an autobiographical fluency task, and a neuropsychological test battery. We found that ToM deficits were positively associated with semantic ABM in the clinical group, whereas a positive relationship appeared between ToM and episodic ABM in controls. We hypothesize that this reflects the course of the disease as well as that semantic ABM is used for ToM processing, being still accessible in AD. Furthermore, we assume that it is also less efficient, which in turn leads to a specific deficit profile of social cognition.

Autobiographical Memory

Levine, Svoboda és munkatársai (2002) olyan félig strukturált Önéletrajzi Interjút fejlesztettek ki az egyedi, specifikus önéletrajzi emlékek vizsgálatára, amely képes kiemelni az emlék elbeszéléséből az eseményspecifikus tartalmakat. Jelen vizsgálat célja e módszer magyar nyelvű adaptációja. Az eljárás segítségével három egészséges életkori csoport került összehasonlításra: fiatalok (20–27 év: 25 fő), középkorúak (45–55 év: 25 fő) és idősek (60–79 év: 16 fő), valamint egy emlékezetsérült klinikai betegcsoport: kezdeti stádiumú Alzheimer-kórban szenvedő betegek (60–80 év: 16 fő). Megerősítést kapott, hogy egészséges személyeknél a kor előrehaladtával romlik az önéletrajzi események elbeszélésének epizodikus gazdagsága. Továbbá, hogy az Alzheimer-kór kezdeti stádiumában sokkal nagyobb mértékben sérül az epizodikus emlékezés képessége, mint hasonló életkorú egészséges idős személyeknél.

Alzheimer’s Disease (AD) is one of the most common forms of dementia affecting over 46 million people, according to AD International. Over the past few decades, there has been considerable interest in developing nanomedicines. Using nanocarriers, the therapeutic compound could be delivered to the site of action where it gets accumulated. This accumulation, therefore, reduces the required doses for therapy. Alternatively, using nanocarriers decreases the side effects. Nanotechnology has had a great contribution in developing Drug Delivery Systems (DDS). These DDS could function as reservoirs for sustained drug release or control the pharmacokinetics and biodistribution of the drugs. In the current review, we have collected 38 original research articles using nanotechnology as DDS for the clinically used cholinesterase inhibitor drugs donepezil (DPZ), Rivastigmine (Riv), and galantamine (Gal) used for AD treatment from 2002 to 2017 from Scopus and PubMed databases. Regarding DDS used for DPZ, most of the research in recent years dealt with polymeric nanoparticles (NPs) including Poly-D, L-Lactide-Co-Glycolide (PLGA), and chitosans (CHs), then Liposomes (LPs), nanogels, and natural products, respectively. In terms of Riv most of the research performed was focused on polymeric NPs including PLGA, polylactic acid (PLA), Poly-Ε-Caprolactone (PCL), poly-alkyl-cyanoacrylates, CH, gelatin and then LPs. The highest application of NPs in regard to Gal was related to modified LPs and polymeric NPs. Polymeric NPs demonstrate safety, higher stability in biological fluids and against enzymatic metabolism, biocompatibility, bioavailability, and improved encapsulation efficacy. LPs, another major delivery system used, demonstrate biocompatibility, ease of surface modification, and amphiphilic nature.

Abstract Objective Because memory decline is the hallmark of Alzheimer’s disease (AD), an important endeavor for both clinicians and researchers is to improve memory performances in AD. This can be pursued by olfactory stimulation of memory in patients with AD and by studying the effects of olfactory stimulation on autobiographical memory (i.e., memory for personal information). The effects of olfactory stimulation on autobiographical memory in patients with mild AD have been reported by recent research. We thus provide the first comprehensive overview of research on odor-evoked autobiographical memory in AD. We also establish the basis for solid theoretical analysis concerning the memory improvement reported by research on odor-evoked autobiographical memory in AD. Method We examined literature on odor-evoked autobiographical memories in AD and propose the “OdAMA” (Odor-evoked Autobiographical Memory in Alzheimer’s disease) model. Results and discussion According to OdAMA model, odor exposure activates involuntary access to specific autobiographical memories, which promotes enhanced experience subjective of retrieval in patients with AD and improves their ability to construct not only recent and remote events but also future ones. The OdAMA model could serve as a guide for researchers and clinicians interested in odor-evoked autobiographical memory in AD.

The risk of Alzheimer’s disease (AD) increases with nonmodifiable conditions including age and lack of effective efficacious pharmacotherapy. During the past decades, the non-pharmacotherapy mode of treatment of dietary modification received extensive attention in AD research. In order to reduce the AD pathology and cognitive decline, various dietary patterns have been attempted including caloric restriction (CR), dietary approaches to stop hypertension (DASH), ketogenic diets (KD), Mediterranean diet (MedDi) and Mediterranean-DASH diet Intervention for Neurological Delay (MIND) diet. Higher adherence to the MedDi diet was associated with decreases in cardiovascular and neurological disorders including AD and related cognitive decline. However, another emerging healthy dietary pattern MIND diet has also been associated with slower rates of cognitive decline and significant reduction of AD rate. Olive serves as one of the building block components of MedDi and MIND diets and the exerted potential health beneficial might be suggested due to the presence of its bioactive constituents such as oleic acids and phenolic compounds (biophenols). A few trials using medical food showed an optimal result in presymptomatic or early stages of AD. The review supports the notion that MedDi and MIND diets display potential for maintaining the cognitive function as nonpharmacological agents against AD pathology and proposed preventative mechanism through the presence of olive biophenols and presents the gaps along with the future directions.
