# Alzheimer's Disease Diagnosis Using Machine Learning: A Survey
## 4 Literature Review  
As per a study, the Tosa straw rs-fMRI measures spontaneous activities consolidated into several distinct resting state networks (RSNs) that exhibit comparable temporal characteristics [86]. SMRI-derived images have been utilized in previous studies [7; 86; 87]. Structural adaptations in sMRI images pertain to the collective arrangement of neurons or neural elements, physically or through synaptic networks. Researchers have been focusing on using structural images to diagnose [PERSON]'s disease throughout history. The utilization of said images has presented challenges for scholars because of the restricted extraction attributes and the resultant precision of prognostication. Various approaches have been implemented to identify the indications and manifestations of advertising. In \begin{table}

**Test Name** & **Type** & **Description** \\ \hline Magnetic resonance imaging (MRI) & Brain Imaging & Magnetic resonance imaging (MRI) employs a combination of radio waves and a potent magnetic field to generate comprehensive visual representations of the brain. However, exhibiting atrophy in specific brain regions linked to Alzheimer’s, MRI scans also eliminate alternative ailments. In the assessment of dementia, an MRI is typically favored over a CT scan. \\ \hline Computerized tomography (CT) & Brain Imaging & The computed tomography (CT) scan, a specialized form of X-ray imaging, can generate cross-sectional visual representations of the human brain. Typically, it excludes the presence of neoplasms, cerebrovascular accidents, and cranial traumas. Magnetic resonance imaging (MRI) employs radiofrequency waves and a potent magnetic field to generate intricate visual representations of the human brain. However, exhibiting atrophy in specific brain regions linked to Alzheimer’s, MRI scans also eliminate alternative ailments. In the assessment of dementia, an MRI is typically favored over a CT scan. \\ \hline Positron emission tomography (PET) & Brain Imaging & Positron emission tomography (PET) can acquire visual representations of the pathological progression. In the process of conducting a PET scan, a radiopharmaceutical tracer of low intensity is administered intravenously to enable the identification of a specific cerebral characteristic. \\ \hline Genetic test & Genetic & The utilization of genetic testing is not advised for the majority of individuals undergoing evaluation for Alzheimer’s disease. Individuals with a familial background of early-onset Alzheimer’s disease may contemplate the matter. \\ \hline \end{tabular}

Table 1: _Cont._advertisements, sophisticated equipment has been widely used to evaluate the disease's severity [88]. The authors provided a retrospective analysis of the illness and its mechanisms. This work delves into the study and provision of unique techniques for photograph processing, enhancement, and segmentation [89]. The methodology employs magnetic resonance (MR) brain imaging to ascertain the interconnectivity between distinct brain regions [90]. A novel artificial intelligence-based approach has been developed to detect alterations in individuals with a heightened susceptibility to Alzheimer's disease a decade before the manifestation of the ailment. The approach utilizes brain magnetic resonance imaging (MRI) scans to determine the interconnections among diverse brain regions [91]. Alzheimer's disease is the predominant etiology of dementia among elderly individuals and is characterized by neurological dysfunction that results in compromised memory and cognitive functions. The development of an effective protocol for the timely detection of the ailment is of paramount importance. Although a cure for the disease has not yet been discovered, the prompt administration of drugs currently in development will likely enhance their efficacy. The timely identification of the ailment may also enable individuals to adopt modifications in their lifestyle that can impede the advancement of the condition [92; 93].
