Hall of Popularity baseball pitcher Tom Seaver just recently died at the age of 75 because of problems of Lewy body dementia (LBD) and COVID-19
Seaver, also called “Tom Terrific,” turned the formerly absurd New york city Mets into the 1969 “Wonder Mets,” leading his team to its very first World Series championship. In addition, he won 311 video games and had a 2.86 made run average over his 20- year profession (1967-1986), which also included 6 seasons with the Cincinnati Reds and late-career stints with other teams.
According to the New York Daily News, in 2013 Seaver was noted to have trouble remembering things, and his thoughts “tended to roam and end up being garbled in transmission.” When he didn’t keep in mind a guy who had been dealing with him for 7 years, his spouse, Nancy, insisted he see a physician. After an evaluation and a battery of tests, the physician told him that he had Lyme disease (an illness he had actually been diagnosed with back in November 1991). He was treated with antibiotics and vitamins and seemed to reveal some enhancement.
However, in March 2019, his family revealed that he had actually been detected with dementia and would no longer be making any public appearances.
Big League Baseball Commissioner Rob Manfred stated: “I am deeply saddened by the death of Tom Seaver, among the best pitchers of all time. Tom was a gentleman who represented the best of our nationwide leisure activity. He was associated with the New York Mets and their extraordinary 1969 season. After their unlikely World Series champion, Tom ended up being a household name to baseball fans– a duty he performed with difference throughout his life.”
Lewy Body Dementia
LBD is related to abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and state of mind.
Although lower known than its “cousins” Alzheimer’s disease and Parkinson’s disease, LBD is not an unusual disorder.
LBD is a progressive illness, with signs starting slowly and intensifying with time. The disease lasts an average of 5 to 7 years from the time of diagnosis to death, but the time span can vary from 2 to 20 years. How rapidly signs develop and alter differs considerably from individual to individual, depending on total health, age, and the intensity of symptoms.
The exact cause of LBD is unknown, but scientists are finding out more about its biology and genes. An accumulation of Lewy bodies is understood to be associated with a loss of certain neurons in the brain that produce two important neurotransmitters: acetylcholine, which is crucial for memory and learning, and dopamine, which plays a crucial role in behavior, cognition, motion, motivation, sleep, and state of mind.
What are Lewy Bodies?
Lewy bodies are called for Friedrich Lewy, a German neurologist. In 1912, he discovered unusual protein deposits that interrupt the brain’s regular functioning in individuals with Parkinson’s disease. These abnormal deposits are now called “Lewy bodies.”
Lewy bodies are made of alpha-synuclein.
Lewy bodies affect several various brain areas in LBD:
- Cerebral cortex, which controls many functions consisting of info processing, understanding, thought, and language
- Limbic cortex, which plays a significant function in feelings and habits
- Hippocampus, which is important to forming new memories
- Midbrain, including the substantia nigra, which is associated with motion
- Brainstem, which is important in regulating sleep and keeping alertness
- Olfactory paths
Types of LBD
The illness consists of 2 related conditions– dementia with Lewy bodies and Parkinson’s illness dementia. The difference lies largely in the timing of cognitive and motion symptoms. In dementia with Lewy bodies, cognitive symptoms are generally kept in mind within a year of parkinsonism, any condition that involves the types of motion changes, such as tremor or muscle stiffness, seen in Parkinson’s illness. In Parkinson’s illness dementia, movement signs are noticable in the early stages, with cognitive signs developing years later on.
Dementia with Lewy bodies
People with dementia with Lewy bodies have a decrease in thinking capability that might look rather like Alzheimer’s illness. However over time they also establish movement and other unique symptoms that recommend dementia with Lewy bodies. Signs that identify this form of dementia from others may include:
- Visual hallucinations, especially early in the course of disease
- Fluctuations in cognitive capability, attention, and alertness
- Slowness of movement, problem strolling, or rigidness (parkinsonism)
- Rapid-eye-movement (Rapid Eye Movement) sleep behavior condition (see listed below)
- Relatively more trouble with complex mental activities, such as multitasking, issue fixing, and analytical thinking, than with memory
Parkinson’s illness dementia
This type of LBD starts as a motion disorder, with symptoms consistent with a medical diagnosis of Parkinson’s illness, such as slowed motion, muscle tightness, tremor, and a shuffling walk.
Typical Signs of LBD
People with LBD may not have every LBD symptom, and the seriousness of symptoms can vary significantly from individual to person. The most common symptoms are modifications in cognition, movement, sleep, and habits.
Memory issues might not be apparent at very first however typically arise as LBD advances
- Cognitive changes: Unpredictable changes in concentration, attention, alertness, and wakefulness from day to day and in some cases throughout the day. Cognitive fluctuations are common in LBD: The person might appear much better one day, then even worse the next
- Hallucinations: Seeing or hearing things that are not present. Acoustic hallucinations are less common than visual ones but might also occur
Some people with LBD might not experience substantial movement problems for numerous years. Particular signs of parkinsonism may consist of:
- Muscle rigidness or tightness
- Mixing gait, sluggish movement, or frozen stance
- Trembling or shaking, many frequently at rest
- Balance problems and falls
- Stooped posture
- Loss of coordination
- Smaller sized handwriting than had been usual for the person
- Lowered facial expression
- Problem swallowing
- Weak voice
Sleep disorders are common in individuals with LBD but are often undiagnosed. These might consist of:
- Rapid Eye Movement habits condition: A condition in which a person seems to act out dreams. It may consist of brilliant dreaming, talking in one’s sleep, violent movements, or falling out of bed
- Insomnia: Trouble falling or remaining asleep or getting up too early
- Uneasy leg syndrome: A condition in which an individual, while resting, feels the urge to move his or her legs to stop unpleasant or uncommon sensations. Strolling or moving usually relieves the pain.
Behavioral and state of mind symptoms
Changes in behavior and mood are possible in LBD. These modifications might include:
- Anxiety: A relentless sensation of unhappiness, failure to take pleasure in activities, or trouble with sleeping, eating, and other regular activities
- Passiveness: A lack of interest in normal daily activities or occasions; less social interaction
- Anxiety: Extreme apprehension, unpredictability, or fear about a future occasion or circumstance
- Agitation: Restlessness, as seen by pacing, hand wringing, an inability to get settled, constant repeating of words or expressions, or irritation
- Delusions: Strongly held false beliefs or opinions not based upon evidence. One deception seen in individuals with LBD is Capgras syndrome, in which the person thinks a relative or good friend has been changed by an imposter
- Fear: A severe, irrational suspect of others, such as suspicion that people are taking or concealing things
Other LBD symptoms
Individuals with LBD can also experience substantial modifications in the part of the nerve system that regulates autonomic functions such as those of the heart, glands, and muscles, consisting of:
- Modifications in body temperature level
- Problems with blood pressure
- Lightheadedness, fainting
- Regular falls
- Sensitivity to cold and heat
- Sexual dysfunction
- Urinary incontinence
- Poor sense of odor
While LBD presently can not be prevented or treated, some signs might react to treatment for a time period. A comprehensive treatment plan might include medications, physical and/or other types of therapy, and therapy. Changes to make the home much safer, equipment to make everyday tasks easier, and social support are also important.
