Demographic Trends

Three major demographic trends are apparent

1. ↓ Fertility Rates

2. Improved health care systems

3. ↑ Life Expectancy

* Chiropractic (61%)

* Herbal medicine (54.8%)

* Massage Therapy (35.7%)

* Acupuncture (33%)

Reasons for CAM usage

* Pain relief (54.8%)

* Chiropractic

* Herbal medicine

* Massage Therapy

Reasons for CAM usage

* Psychological wellbeing

* Improve quality of life

* Maintenance of health and fitnessReference: Zhang et al., 2007

Common health issues

• Gait and Balance

• Sleep

• Cognition (memory)

• Depression

• Arthritis

• 1041 articles in Pubmed

Gait and balance

• Major reason for falls and immobility

• Musculoskeletal system to nervous system regulate

• Aging process influences both

• Yoga has demonstrated the ability to reverse the same

• Prevention of falls will be a major contribution

Gait and Balance

• Selected Balancing postures along with loosening and strengthening exercises along with better attention and awareness through meditation improved

– Ability to get up from a chair without support

– Initiate quick walk with long steps

– Speed of walking

– Balancing

Med Sci Monit. 2007;13(12):LE19-20

Styles studied

• Integrated Yoga S-VYASA

• Iyengar Yoga

• Mindfulness

• Isha Yoga

• Relaxation response and exercise

Depression

• Socialization through group Yoga

• Dynamic Yoga for the elderly

• Keertan Yoga (Bhakthi yoga)

Styles studied

• Integrated Yoga Module S-VYASA

• Sudarshan Kriya Yoga

• Sahaja Yoga

• Mindfulness

• Keertan Yoga

Sleep• Elderly spend more time awake in the bed than

sleeping

• Both quality and quantity of sleep gets affected due to medical, psychological and aging related changes in the brain

• Yoga improved:– Time taken to fall asleep

– Number of hours slept

– Feeling of being rested in the morning

– Number of awakenings in the night

Indian Journal of Medical Research, 121: 683-690

Arthritis in the elderly

• Older people most often have

Osteoarthritis,

Rheumatoid arthritis, or gout.

• Osteoarthritis (OA) is the most common type of arthritis in older people. OA starts when tissue, called cartilage, that pads bones in a joint begins to wear away.

Aging and Mental AgilityAlzheimer's and Dementia

The best gift we are bestowed with

The ability to Remember

The ability to forget

Alzheimer’s Disease

• An irreversible, progressive brain disorder

• Slowly destroys memory and thinking skills, and

• Eventually the ability to carry out the simplest tasks.

• In most people with Alzheimer’s, symptoms first appear after 65 and most common after 85

• Alzheimer’s disease is named after Dr. AloisAlzheimer In 1906

• A Psychiatrist from Germany

Prevalence

• Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people.

• 1 in 10 above 65 years and 1 in 2 after 85 years are known to suffer from Alzheimer’s

Dementia

• Alzheimer’s is the most common cause of dementia among older adults.

• Loss of cognitive functioning thinking,

• Remembering,

• Reasoning

• and behavioral abilities

• to such an extent that it interferes with a person’s daily life and activities.

Changes in the brain

The process

• Amyloid plaques

• Neurofibrillary tangles

• Loss of neuronal connections and cell death.

The 4 fold issue

• Aging related memory loss

• Mild cognitive impairment

• Alzheimer’s Disease

• Dementia

Yoga in Alzheimer's Disease

• Stress increases cortisol which is toxic to hippocampal

cells (normal memory function)

• A stress induced hypercortisolemia can aggravate

Alzheimer's

• Regular practice of meditation produces stress reduction

that reduces serum cortisol. Hence, provide benefit in

patients with Alzheimer's

[Ann Indian Acad Neurol. 2012;15(4): 247–54.]

Yoga in Age Related Degeneration

In Elder:

• Cortisol & adrenocorticotropic

hormone (ACTH) raised

• Brain-derived neurotropic factor

(BDNF), serotonin & dopamine

lowered

Yoga:

• Significantly reduces cortisol; ACTH

• Increases serotonin, dopamine &

BDNF

• Hence, Yoga helps in prevention of

age-related degeneration

• [Age (Dordr). 2014;36(4):9683.]

• Yoga is a promising intervention for

neurodegenerative diseases.

[Integr Med (Encinitas). 2014;13(3):33-9.]

• Long-term Sahaja Yoga

Meditation:

– Inceases overall grey matter

volume

– Regional enlargement in several

right hemispheric cortical &

subcortical brain regions

– Associated with sustained

– attention, self-control,

compassion & interoceptive

perception.

• [PLoS One. 2016;11(3):e0150757.]

• Yoga practitioners have stronger

functional connectivity within

basal ganglia cortico-thalamic

feedback loops than non-

practitioners

[Front Hum Neurosci. 2015;9:137.]

During meditation: it became

localized to the right inferior

frontal cortex/right insula and

right middle/superior temporal

cortex.

– Right inferior frontal activation

was directly associated with the

subjective depth of the mental

silence experience.

[J Altern Complement Med.

2015;21(3):175-9.]

• Yoga produces acute increases

in thalamic GABA levels &

improvements in mood and

anxiety

[J Altern Complement Med.

2010;16(11):1145-52.]

Structural changes in the brain

• Increased thickness in cortical areas related to attention as well as increased subcortical gray matter in right insula and hippocampus in long-term meditators

Neuroreport. 2005 Nov 28;16(17):1893-7.

Volume of hippocampus increases

Voxel based morphometric analysis of the effects of yoga practice in healthy elderly (demonstrates significant increase in bilateral hippocampus gray matter volume after 6 months of yoga practice [indicated by the yellow circle]) Indian J Psychiatry. 2013 Jul; 55(Suppl 3): S394–S396.

Brain areas active during meditation

• Evoked Potential studies – Diencephalon

• Imaging studies –– Anterior Cingulate

– Dorso-lateral Prefrontal Cortex

– Regions of limbic systems

– Int J Psychophysiol. 2011 May;80(2):103-11

– J Altern Complement Med. 2010 Dec;16(12):1253-8

• Yoga is as effective as memory enhancement

training in improving functional connectivity

in relation to verbal memory performance in

subject with mild cognitive impairment

[J Alzheimers Dis. 2016;52(2):673-84.]

History

Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms included:

• memory loss,

• language problems, and

• unpredictable behavior.

he examined her brain and found many abnormal clump and tangled bundles of fibers

Discovery of how chromosomes are protected by telomeres and the enzyme telomerase

Telomeres and aging

Life style modification and telomere activity

Telomerase activity is associated with complex changes in lifestyle

Cell Biology International (2011) 35, 1079–1083

Telomerase and meditation

• 30 meditators (mindfulness)

• 6 hours daily for 3 months

• ↑ Telomerase activity in retreat participants compared to controls

• ↑ Perceived Control, ↓ Neuroticism, and ↑ in both Mindfulness and Purpose in Life were greater in the retreat group (p < 0.01)

Psychoneuroendocrinology, 2011

Yoga

↑ Positive Emotions (Narasimhan L, 2011)

↓ Il-6; TNF-α (Kiecolt-Glaser, 2010)

↓ Oxidative stress (Sinha S, 2007)

↑ Adiponectin (Packard C, 2011)

Promote Weight reduction (Jain SC, 1993)

Regulates Blood Sugar & BP (Gokal R, 2007)

• Carbohydrate intolerance, osteoporosis and high blood pressure - modified by behavioral and life style interventions such as exercise, diet, and stress reduction

• Neurobehavioral aging, including cognitive decline – Exercise, Yoga and meditation,

Reference: Schneider et al., 2002; Finch, 1987

Exercise, lifestyle management and relaxation

Yoga and Tai-chi

• A preventive health care program (Haber,

1983)

• A randomized controlled trial (Blumenthal et al., 1991)

• Heart rate variability (Bowman et al., 1997)
