Consider the neural and behavioral differences between Multi Sclerosis, Alzheimers, and Parkinsons disease.

If you had to suffer from one of these diseases, which one would you rather suffer from and why? .

Now, take a look at the articles in Science Daily referring to Parkinsons and MS:,

If you had to decide to provide government funding for ONLY ONE of these research programs , which one would you fund and wh

The Effects Of Alzheimers On The Brain

Damage to the brain begins years before symptoms appear. Abnormal protein deposits form plaques and tangles in the brain of someone with Alzheimers disease. Connections between cells are lost, and they begin to die. In advanced cases, the brain shows significant shrinkage.

Its impossible to diagnose Alzheimers with complete accuracy while a person is alive. The diagnosis can only be confirmed when the brain is examined under a microscope during an autopsy. However, specialists are able to make the correct diagnosis up to 90 percent of the time.

The symptoms of Alzheimers and dementia can overlap, but there can be some differences.

Both conditions can cause:

  • behavioral changes
  • difficulty speaking, swallowing, or walking in advanced stages of the disease

Some types of dementia will share some of these symptoms, but they include or exclude other symptoms that can help make a differential diagnosis. Lewy body dementia , for example, has many of the same later symptoms as Alzheimers. However, people with LBD but are more likely to experience initial symptoms such as visual hallucinations, difficulties with balance, and sleep disturbances.

People with dementia due to Parkinsons or Huntingtons disease are more likely to experience involuntary movement in the early stages of the disease.

Treatment for dementia will depend on the exact cause and type of dementia, but many treatments for dementia and Alzheimers will overlap.

Treating Alzheimers Disease Vs Other Types Of Dementia

Neither Alzheimerâs nor most other types of dementia have a cure. Doctors focus treatments on managing symptoms and keeping the disease from getting worse.

Some of the treatments for dementia and Alzheimerâs overlap.

  • Cholinesterase inhibitors can help with memory loss in certain types of dementia and Alzheimerâs.
  • Glutamate inhibitors help with learning and memory in both dementia and Alzheimerâs.
  • Sleep medications may help with sleep changes.
  • Antidepressants can help with depression symptoms.
  • Antipsychotic medications may help with behavior changes.

Some types of dementia respond to treatment, depending on what is causing it. Your doctor may recommend:

  • Stopping the use of drugs and alcohol
  • Tumor removal

Mechanism Burden Scores Allow For Reproducible Subtyping Of Ad And Pd Patients

Using the data of 148 SNPs mapping to 15 common AD/PD disease mechanisms in 486 AD and 358 PD patients within our discovery cohorts, we developed an unsupervised machine learning approach to discover subgroups . This approach consisted of two basic steps: sparse autoencoding of the SNPs mapping to each of the 15 mechanisms, resulting into a profile of genetic burden scores consensus sparse non-negative matrix factorization to cluster patients and for identifying most discriminative mechanisms. Our method resulted in 4 subgroups in ADNI, PPMI as well as in a merger of ADNI and PPMI patients that were statistically stable and better discriminated than expected by pure chance details are described in the section and in the Supplementary Text . Interestingly, clusters found in the merged AD/PD cohort were all composed of a mixture of AD and PD patients . They were not identical to the ones identified in each disease individually, but showed a highly significant overlap in both cases -test). That means our clustering suggests the existence of certain commonalities between AD and PD patients on the level of SNP burden on specific mechanisms. We will discuss the question of disease relevance later.

Cluster 2 isamong other featuresstrongly associated with the genetic burden on IL1B, NLRP3, TP53,,,. Activation of IL1B by NLRP3 and TP53 play a role in the response of the immune system. Neuroinflammation is a common feature of AD and PD.

Diagnosis: Parkinson’s Dementia Or Dementia With Lewy Bodies

Dementia vs Alzheimers: What is the Difference?

During assessment, a specialist may look at when the dementia symptoms first appeared before reaching a diagnosis of Parkinson’s dementia or dementia with Lewy bodies.

If there have been motor symptoms for at least one year before dementia symptoms occur, specialists will often give a diagnosis of Parkinson’s dementia.

If dementia symptoms occur before or at the same time as motor symptoms, specialists will usually give a diagnosis of dementia with Lewy bodies.

However, it should be noted that in some cases of dementia with Lewy bodies, no motor symptoms develop at all.

Theres no single test – diagnosis is made through several different assessments, usually starting with an appointment with your GP or Parkinson’s nurse.

Some people find it helps to go to the appointment with someone who knows them well, who can give the GP or Parkinson’s nurse information about changes they’ve noticed.

Your GP can discuss your symptoms with you and carry out a physical examination, including blood and urine tests, to rule out other potential causes of the symptoms .

Your GP may also review your medication, in case your symptoms are side effects.

If your GP thinks you have dementia, they can refer you to a specialist, such as a neurologist, psychiatrist or geriatrician.

You might be referred to a memory clinic or memory service. In some areas of the country, you can refer yourself to these services.

But if you feel you need to see the specialist again, you can ask to be referred back.

Differences Between Alzheimers And Parkinsons

Were going to group the differences between both illnesses into different blocks and explain what each of them consists of. All of them have been extracted from two reference psychopathology manuals: Belloch, Sandín, and Ramos and the DSM-5 .

The first block of differences between Alzheimers and Parkinsons refers to their type of symptoms. Lets see what they are.

Identification Of Common Molecular Mechanisms

Common molecular mechanisms between AD and PD were identified with the help of a systematic literature mining approach with post-hoc manual curation. More specifically, the text mining engine SCAIView was used to construct cause-effect relationships between molecules, pathways, biological processes and imaging features in both, AD and PD, see Domingo-Fernandez et al. and Kodamullil et al. for details, for details. After manual curation, two computable disease maps, one for AD and one PD were created. Finally, we have also made them interactively usable via a dedicated web application .

Calculation of the intersection of cause-effect relationships described in the AD and PD disease maps resulted into 27 genes grouped into 15 cause-effect relationship sub-graphs, called mechanisms from now on . While some of these mechanisms describe only posttranslational modifications of a single protein, others reflect more complex proteinprotein interactions and signaling cascades . Key proteins described in both diseases include e.g. APOE, TAU, SNCA and TOMM40. These proteins are involved into several known disease relevant processes that we have made computationally accessible via our earlier developed NeuroMMSig database.

We mapped 148 genetic variants measured in ADNI1, ADNI2/GO as well as PPMI to the 27 common AD/PD disease genes via a combination of two strategies: a) proximity and b) eQTL mapping, see details in Supplements on page 2.

Parkinsons Dementia Vs Alzheimers Dementia

According to experts, Parkinsons dementia can cause impaired physical activity and impacts motor skills. Two neurotransmitters called dopamine and serotonin tend to be damaged by Parkinsons.

In addition to causing issues with movement and coordination, this form of dementia can also cause a slower thought process and memory problems. This is usually less pronounced however, until the later stages of the disease.

With Alzheimers, two types of proteins in the brain, tangles and plaques , accumulate and kill brain cells. This Alzheimers-induced dementia affects memory, clear thinking, language skills, and orientation. It reduces comprehension, learning capacity, and judgement. Storing new information and memory retrieval are impacted more than motor skills.

Distinguishing between these neurodegenerative conditions is important to determine the best treatment approach. Medications for one of condition might create problems when given to a patient with the other condition.

Our Eyes May Provide Early Warning Signs Of Alzheimers And Parkinsons

What’s the Difference Between Alzheimer’s Disease and Dementia?

Forget the soul it turns out the eyes may be the best window to the brain. Changes to the retina may foreshadow Alzheimers and Parkinsons diseases, and researchers say a picture of your eye could assess your future risk of neurodegenerative disease.

Pinched off from the brain during embryonic development, the retina contains layers of neurons that seem to experience neurodegenerative disease along with their cousins inside the skull. The key difference is that these retinal neurons, right against the jellylike vitreous of the eyeball, live and die where scientists can see them.

Early detection is sort of the holy grail, said Ron Petersen, director of Mayo Clinics Alzheimers Disease Research Center and the Mayo Clinic Study of Aging. By the time a patient complains of memory problems or tremors, the machinery of neurodegenerative disease has been at work probably for years or decades.

Experts liken it to a cancer that only manifests symptoms at Stage 3 or 4. When patients begin to feel neurodegenerative diseases impact on their daily life, its almost too late for treatment.

Catching the warning signs of neurodegenerative disease earlier could give patients more time to plan for the future whether thats making caregiving arrangements, spending more time with family or writing the Great American novel.

Whats The Difference Between Lewy Body Dementia Parkinsons Disease And Alzheimers Disease

Lewy body dementia is an umbrella term for two related clinical diagnoses: dementia with Lewy bodies and Parkinsons disease dementia. These disorders share the same underlying changes in the brain and very similar symptoms, but the symptoms appear in a different order depending on where the Lewy bodies first form.

Dementia with Lewy bodies is a type of dementia that causes problems with memory and thinking abilities that are severe enough to interfere with everyday activities. It specifically affects a persons ability to plan and solve problems, called executive function, and their ability to understand visual information. Dementia always appears first in DLB. The motor symptoms of Parkinsons such as tremor, slowness, stiffness and walking/balance/gait problems usually become more evident as the disease progresses. Visual hallucinations, REM sleep behavior disorder, fluctuating levels of alertness and attention, mood changes and autonomic dysfunction are also characteristic of DLB.

Finally, Alzheimers is characterized by different abnormal clumps called amyloid plaques, and jumbled fiber bundles called tau tangles. These microscopic structural changes in the brain were discovered by Dr. Alois Alzheimer in 1906. These plaques and tangles, together with loss of connections between nerve cells, contribute to loss of coherence and memory, as well as a progressive impairment in conducting normal activities of daily living.

Data Extraction And Literature Quality Evaluation

The authors N.-N. Hou and X. Zuo completed literature retrieval and selection independently. When there was a disagreement, L. Cui and H.-M. Wu participated to reach a consensus. Extracted from the studies were author name, publication year, gender, age range, study design, response rate, diagnostic criteria, case number, study location, urban/rural, education, and sample size. All eligible studies were systematically evaluated for quality based on their sample size, study design, response rate and diagnostic assessment. The detailed scoring criteria were performed as previously described by Prince et al. .

How Do Treatments Differ

Twilight Zone: October 2016

MS treatments can ease your symptoms during an attack or slow down the diseaseâs effects on your body.

Steroids like prednisone calm the inflammation that damages your nerves.

Plasma exchange is another therapy if steroids donât work. Your doctor will use a machine to remove the plasma portion of your blood. The plasma gets mixed with a protein solution and put back into your body.

Some people with both diseases who take anti-inflammatory medicines like steroids see their Parkinsonâs symptoms get better.

Disease-modifying treatments slow down MS nerve damage and disability. They include:

The Pathologies Are Different But Many Of The Symptoms Can Be Similar

We do know that the pathology is quite different between Parkinsons and dementia, said Dr. Odinachi Oguh, a neurologist at the Cleveland Clinic Lou Ruvo Center for Brain Health. But the processes in which memory is impacted in both diseases is about the same.

From the pathology standpoint, both diseases are characterized by a neurodegenerative process, Oguh said. The neurodegeneration results in abnormal accumulation of protein, which builds up and becomes toxic to the brain.

Alzheimers, for example, affects memory areas of the brain, which include the temporal lobes, as well as the memory center, or hippocampus. Parkinsons, meanwhile, starts in the basal ganglia part of the brain, and as the disease progresses, it can also affect the memory center, resulting in forgetfulness, an early sign of Alzheimers or other forms of dementia.

Will The Research Lead To A Breakthrough

Experts in these fields told Healthline this particular research does provide some encouragement.

James Hendrix, director of global science initiatives at the Alzheimers Association, said although the three diseases involve different proteins and have different effects on the brain, there is still some commonality.

He likened it to studying the motors of cars, airplanes, and boats. Although theyre different modes of transport, they still have similar engines.

Its valuable to have this cross talk. You dont want to work in a silo, Hendrix told Healthline. A discovery in one area can revolutionize another field.

George Yohrling, PhD, the senior director of mission and scientific affairs at the Huntingtons Disease Society of America, agrees.

Theyre looking at whats going on at the cellular level. What cellular machinery is being disrupted, he told Healthline.

It gets down to the cellular level, added Hendrix. If you can understand whats going wrong, you might be able to prevent that mechanism from happening.

A breakthrough is sorely needed for all these diseases.

Late last month, the Centers for Disease Control and Prevention announced that the death rate from Alzheimers in the United States increased 55 percent between 1999 and 2014.

In addition, about 50,000 people in the United States are diagnosed with Parkinsons every year. An estimated 500,000 Americans are living with the disease.

That would be wonderful, said Yohrling.

Symptoms Of Parkinsons Disease

  • Apathy
  • Feeling, seeing, smelling, hearing and tasting things that arent there
  • Hallucinations and delusions

Parkinsons disease is usually expressed through the following five stages:

  • Stage one Mild symptoms dont interfere with daily tasks, tremors occur on one side of the body, and posture, gait and facial expression changes may happen.
  • Stage two Symptoms worsen, tremors and stiffness affect the entire body and walking and standing are more difficult. At this stage, people may have some trouble performing daily activities.
  • Stage three Trouble moving quickly, and balance issues can make it hard to eat or get dresses. Patients may be more likely to fall.
  • Stage four Patients may need a walker to move around. Most people are unable to live alone at this stage because they need help with daily activities.
  • Stage five It may be impossible to stand or walk. A wheelchair may help with mobility. A caregiver should be present at all times during this stage.

  • 2Department of Preventive Medicine, Wenzhou Medical University, Wenzhou, China
  • 3Shanghai 9th People’s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China

Background: Alzheimer’s disease and Parkinson’s disease are two major neurodegenerative diseases worldwide. Demographic aging is in rapid progress in China. Up-to-date estimates of AD and PD prevalence have not been provided.

Methods: Studies that reported the prevalence of AD and PD in China were identified via a systematic database search from 1985 to 2018. Meta-analysis, local polynomial regression and autoregressive integrated moving average model were used for analyses.

Results: A total of 99 studies were included in the study with populations of 385,312 and 227,228, respectively for AD and PD. The overall prevalence of AD and PD following age standardization was 3.20% and 1.06% , respectively in individuals over 60 years old. The rates increased drastically for every 10-years increment of age. The yearly prevalence of AD was predicted to increase from 3.81 to 6.17% in the next 5 years. Significant differences were observed between genders , and between education levels , but not between urban and rural settings.
