Cognitive decline refers to a gradual decrease in cognitive abilities like memory, attention, thinking, reasoning, and language. It is a natural part of aging, but can be accelerated by certain health conditions. Some key features of cognitive decline include:
- Memory loss: Forgetting recent events or conversations, misplacing items, difficulty recalling names or words.
- Difficulty focusing: Trouble paying attention or concentrating. Easily distracted.
- Impaired reasoning: Trouble following conversations, instructions, or logic. Making poor decisions.
- Issues with spatial orientation: Getting lost in familiar places. Difficulty judging distances or comprehending 3D images.
- Problems with language: Forgetting words or substituting words incorrectly. Rambling speech or muddled sentences.
- Slower processing speed: Taking longer to understand and react to information. Difficulty doing multiple tasks at once.
- Decreased judgment: Changes in personality like inappropriate social behavior. Loss of initiative or interest in usual activities.
Cognitive decline is not the same as dementia, though the two are related. Dementia refers to significant impairment in two or more cognitive functions that interferes with daily life. It involves more severe symptoms than age-related cognitive decline. Alzheimer's disease is the most common form of dementia.
Some factors that contribute to cognitive decline include:
- Aging: The brain shrinks and brain cells die with advancing age. By age 60, the brain is much less efficient.
- Genetics: Many genes have been associated with increased risk of cognitive impairment.
- Lifestyle factors: Lack of exercise, obesity, smoking, excessive alcohol, and poor diet. Social isolation and sleep deprivation also play a role.
- Medical conditions: High blood pressure, heart disease, stroke, diabetes, depression, etc.
- Head injury: Concussions and traumatic brain injuries raise risk.
- Education level: Less education correlates with higher rates of decline. Mentally stimulating activities build cognitive reserve.
The good news is that cognitive decline is not inevitable. Steps you can take to maintain cognitive health include:
- Eating a Mediterranean diet high in vegetables, berries, whole grains, fish, and olive oil. The Hormone Hub recommends specific nutrition plans tailored for cognitive health.
- Engaging in regular aerobic exercise and strength training to improve blood flow to the brain.
- Reducing alcohol intake and stopping smoking.
- Managing medical conditions carefully, like heart health and diabetes.
- Staying mentally, socially, and physically active. Challenging your brain with puzzles, games, learning new skills, etc.
- Considering hormone therapy to optimize testosterone, estrogen, thyroid and growth hormone levels, which all influence cognition. The Hormone Hub offers cutting-edge therapies.
- Getting 7-9 hours of quality sleep every night.
- Managing stress through yoga, meditation, music, etc.
