“…Neuroimaging is a clinical specialty that focuses on creating images of the brain using noninvasive techniques (e.g., magnetic resonance imaging and computed tomography). Brain imaging has become possible since the discovery of X-rays and with new technologies and large-scale imaging projects such as the Human brain project, Human connectome project, and Chinese brain project, more detailed information about the brain has been obtained (Bilgiç, 2018).…”

Alzheimer's disease is an untreatable, progressive brain disorder that slowly robs people of their memory, thinking abilities, and ultimately their capacity to complete even the most basic tasks. Among older adults, it is the most frequent cause of dementia. Although there is presently no treatment for Alzheimer's disease, scientific trials are ongoing to discover drugs to combat the condition. Treatments to slow the signs of dementia are also available. Many researchers throughout the world became interested in developing computer-aided diagnosis systems to aid in the early identification of this deadly disease and assure an accurate diagnosis. In particular, image-based approaches have been coupled with machine learning techniques to address the challenges of Alzheimer's disease detection. This study proposes a computer-aided diagnosis system to detect Alzheimer's disease from biomarkers captured using neuroimaging techniques. The proposed approach relies on deep learning techniques to extract the relevant visual features from the image collection to accurately predict the Alzheimer's class value. In the experiments, standard datasets and pre-trained deep learning models were investigated. Moreover, standard performance measures were used to assess the models' performances. The obtained results proved that VGG16-based models outperform the state-ofthe-art performance.

Dementia is a chronic or progressive neurodegenerative condition which is organic in origin. There will be impairment of thinking, memory orientation, comprehension, language, calculation, and judgement. Alzheimer's disease facts and gures in 2021 according to Alzheimer's association shows Alzheimer's disease accounts for 60% to 80% of the total cases. Behavioural and psychological symptoms of dementia also known as neuropsychiatric symptoms are a group of symptoms with behavioural and psychological manifestations. Disturbances include behavioural symptoms like wandering, hoarding, physical aggression, sexually disinhibition, culturally inappropriate behaviour, agitation and psychological symptoms like apathy, depression, anxiety, delusions, and hallucinations, sundowning, elation. Scales like the Neuropsychiatric Inventory, the Behavioural Pathology in Alzheimer Disease rating scale, the Consortium to Establish a Registry for Alzheimer Disease Behaviour Rating Scale for Dementia, Dementia Behaviour Disturbance scale, and the Neurobehavioral Rating Scale can be utilized to recognise BPSD.Neuropsychological assessment also have an important role. Non-pharmacological methodologies contain different sorts of treatment: tactile stimulation, pressure point massage, fragrant healing, light treatment, garden exercises, music therapy, dance therapy, and Snoezelen multisensory therapy, psychological strategies of multicomponent treatment strategies. Broadly focussing on sensory stimulation, social activities, structural activities, behavioural activities, environmental activities, and training programmes. Pharmacological treatment includes antipsychotics, mood stabilizers and antidepressants in treating BPSD, and cholinesterase inhibitors and memantine for the situation of Alzheimer's dementia sedative/hypnotics for sleep issues. Treatment can be further categorized based on individual NPS like agitation, psychosis, apathy, depression, sleep problems and other symptoms. Future treatment which has less evidence as of now includes rTMS, TDCS and Photo biomodulation therapy
