Aim: Diabetes mellitus (DM), a systemic disease, is a major public health concern. It is possible that micro and macrovascular changes in the inner ear due to DM could affect both auditory and vestibular functioning. However, there is a lack of conclusive evidence for vestibular impairment in individuals with DM.

Brain related disorders are a set of medical ailments that cause motor incoordination, cognitive and memory problems due to neurodegeneration in the brain. Although current therapies alleviate symptoms, they fail to target the fundamental pathological processes driving the disorders. A hematopoietic growth factor, Erythropoietin, stimulates erythroid cell formation and is therapeutically applied for the treatment of anemia.

Alzheimer's disease (AD), the most common form of dementia, is a multifactorial neurological condition characterized by progressive loss of memory and learning, uncontrollable movement, difficulty processing visual images, and impairment of reasoning and/or judgment skills. Although the exact cause of AD is still unknown, recent evidence suggests that environmental, lifestyle, and genetic factors are common contributors to the disease's progression. Pathophysiological features of AD include amyloid beta (Aβ) accumulation, abnormal deposition of neuritic plaques and neurofibrile tangles, cholinergic dysfunction, neuroinflammation, and oxidative stress burden along with mitochondrial dysfunction.

Alzheimer's Disease (AD), a prevalent neurodegenerative disorder, poses a significant global health challenge with complicated pathogenesis. Pathological characteristics of AD include increasing loss of cholinergic neurons, oxidative stress, mitochondrial dysfunction, and amyloid beta accumulation. Due to the limited availability of effective therapeutic options with only symptomatic relief and their severe adverse effects, there is a significant need to search and explore new agents for the management of AD.

Objectives: The use of a 500 Hz tone burst over other frequencies was adopted for the clinical recording of ocular vestibular-evoked myogenic potential (oVEMP) on the basis that this stimulus frequency produces larger response amplitudes (frequency tuning) than the other frequencies. However, the possibility of reflex contamination due to a spatially displaced reference electrode from the muscle of the response origin raises questions about using an infraorbital (IO) montage. Nonetheless, the belly-tendon (BT) montage, which places both the recording electrodes over the inferior oblique muscle, increases the chances of obtaining a response with greater contribution from the inferior oblique muscle.

Parkinson's disease (PD) stands as the second most common neurological disorder after Alzheimer's disease, primarily affecting the elderly population and significantly compromising their quality of life. The precise etiology of PD remains elusive, but recent research has shed light on potential factors, including the formation of α-synuclein aggregates, oxidative stress, neurotransmitter imbalances, and dopaminergic neurodegeneration in the substantia nigra pars compacta (SNpc) region of the brain, culminating in motor symptoms such as bradykinesia, akinesia, tremors, and rigidity. Monoamine oxidase (MAO) is an essential enzyme, comprising two isoforms, MAO-A and MAO-B, responsible for the oxidation of monoamines such as dopamine.

Further, SiMFy was validated using only the infraorbital (IO) electrode montage. However, the recordings obtained using the IO montage might be susceptible to reference contamination introduced by a small separation between the recording electrodes and also susceptible to reflex impurity due to the spatially displaced reference electrode from the inferior oblique muscle, rendering it vulnerable to picking up responses from other muscles.

Brain-related disorders include neuroinflammation, neurodegenerative disorders, and demyelination, which ultimately affect the quality of life of patients. Currently, brain-related disorders represent the most challenging health problem worldwide due to complex pathogenesis and limited availability of drugs for their management. Further, the available pharmacotherapy accompanies serious side effects, therefore, much attention has been directed toward the development of alternative therapy derived from natural sources to treat such disorders.

Parkinson's disease (PD), the most common brain-related neurodegenerative disorder, is comprised of several pathophysiological mechanisms, such as mitochondrial dysfunction, neuroinflammation, aggregation of misfolded alpha-synuclein, and synaptic loss in the substantia nigra pars compacta region of the midbrain. Misfolded alpha-synuclein, originating from damaged neurons, triggers a series of signaling pathways in both glial and neuronal cells. Activation of such events results in the production and expression of several proinflammatory cytokines via the activation of the nuclear factor κB (NF-κB) signaling pathway.

Recently, Parkinson's disease (PD) has become a remarkable burden on families and society with an acceleration of population aging having several pathological hallmarks such as dopaminergic neuronal loss of the substantia nigra pars compacta, α-synucleinopathy, neuroinflammation, autophagy, last but not the least astrogliosis. Astrocyte, star-shaped glial cells perform notable physiological functions in the brain through several molecular and cellular mechanisms including nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. It has been well established that the downregulation of the astrocytic Nrf2 signaling pathway plays a crucial role in the pathogenesis of PD because it is a master regulator of cellular defense mechanism along with a regulator of numerous detoxifying and antioxidant enzymes gene expression.
