Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease and no longer considered merely as a motor disorder where dementia may precede motor deficits and enhance their onset. Age is the most significant risk factor for the development of PD and dementia where oxidative stress increases during aging making the brain more susceptible to neurodegeneration. The exact underlying mechanism responsible for neurodegeneration progression still remains elusive and incompletely understood. Several epidemiological studies suggested that exposure to different environmental toxic agents and heavy metals increase the risk of induction and progression of neurodegenerative diseases. On the other hand, moderate cigarette smoking and coffee drinking are inversely associated with the risk of their development. Animal models of Parkinson's disease and Dementia: Typically, animal models of PD include environmental neurotoxins or genetic models (PD-related mutations model). Metal ions play a crucial role in the development of PD and dementia; excessive manganese exposure has been associated with manganism while aluminum has been linked with Alzheimer's disease and dementia. Manganism is characterized by extrapyramidal symptoms resembling idiopathic PD as well as psychiatric and cognitive deficits. Rotenone, a naturally occurring insecticide, and pesticide have been also linked to the two pathological hallmarks occur in clinical PD (motor and non-motor symptoms), but high mortality rate represents the major limitation for this model. On the other hand, the use of genetic animal models and identification of disease-relevant genes can encourage search to discover new promising disease-modifying therapies.

Neuroprotection strategies of Parkinson’s disease and Dementia: Dopamine deficiency plays the central role in the pathogenesis of PD, thus it represents the focus of treatment efforts. Other neurotransmitters also play a major role in controlling symptoms that related to cognitive behaviors, depression, anxiety, and dementia. Oxidative stress, inflammation, and apoptosis are considered the main mechanisms implicated in the degeneration of dopaminergic neurons. Protein malnutrition can predict the progression of neurodegeneration by increasing oxidative damage. In general, protection and early diagnosis still represent the cornerstone and the golden strategy in delaying or preventing the progression of age-dependent neurodegeneration. The most promising PD-modifying therapies include natural products and nutrients having powerful antioxidants, antiinflammatory and antiapoptotic as well as those which promote neurotransmitters synthesis or enhance their concentration. Moreover, therapies which reduce stress, depression and promote better memory have also a significant role in delaying disease progression and in enhancing the efficacy of different treatments. On the other hand, non-drug therapies as physical training and mental activity can improve motor functions and manage non-motor symptoms.

Determination:

Parkinson illness can be difficult to analyze. No single test can recognize it. Parkinson can be effortlessly confused with another wellbeing condition. A medicinal services supplier will as a rule take a clinical history, including a family ancestry to see whether any other individual in your family has Parkinson's illness. The person in question will likewise do a neurological test. In some cases, a MRI or CT output, or some other imaging sweep of the mind can distinguish different issues or preclude different infections.

Treatment

There are no medicines to slow or stop the synapse harm brought about by Parkinson's infection dementia. Current methodologies center around improving manifestations. In the event that your treatment plan incorporates meds, it's critical to work intimately with your doctor to distinguish the medications that work best for you and the best dosages.

•           Cholinesterase inhibitors — drugs that are the ebb and flow backbone for rewarding intellectual changes in Alzheimer's — may help Parkinson's illness dementia side effects, including visual mental trips, rest unsettling influences and changes in intuition and conduct.

•           Antipsychotic drugs — a medication classification at times recommended for conduct manifestations of Alzheimer's — ought to be utilized with outrageous alert since they may cause genuine symptoms in up to half of those with Parkinson's sickness dementia or Lewy body dementia. Reactions may remember abrupt changes for awareness, disabled gulping, intense disarray, scenes of dreams or pipedreams, or appearance or intensifying of Parkinson's manifestations.

Rewarding development side effects in those with Parkinson's dementia can be testing, on the grounds that carbidopa-levodopa — the main treatment for Parkinson's development indications — can some of the time irritate visualizations and disarray in those with Parkinson's dementia or Lewy body dementia. Albeit profound cerebrum incitement (DBS) is presently contraindicated for Parkinson's illness dementia, a little clinical preliminary directed by University College London researchers and distributed in the February 2018 issue of JAMA, indicated that profound mind incitement was protected and very much endured in members with Parkinson's malady dementia.

Despondency is normal in people with Parkinson's malady dementia and Lewy body dementia, and might be treated with a sort of stimulant called particular serotonin reuptake inhibitors (SSRIs). REM issue might be treated with clonazepam.

A system called profound cerebrum incitement may likewise be utilized to treat Parkinson illness. It sends electrical motivations into the cerebrum to help control tremors and jerking developments. A few people may require medical procedure to oversee Parkinson infection side effects. Medical procedure may include wrecking little zones of cerebrum tissue answerable for the manifestations. Notwithstanding, these medical procedures are once in a while done since profound mind incitement is presently accessible.

Anticipation

Specialists don't yet see how to forestall Parkinson sickness. In certain occasions, there is by all accounts a hereditary inclination to create Parkinson sickness, yet this isn't generally the situation. Exploration is in progress to discover better approaches to treat and forestall the ailment.
