Study Notes
Cortisol's Effects on the Hippocampus
- High levels of cortisol can negatively impact the hippocampus, leading to decreased neurogenesis and impaired memory.
- The hippocampus plays a crucial role in the brain, responsible for forming and consolidating new memories.
Stress and the Nervous System
- Chronic stress can lead to decreased hippocampal neurogenesis, impaired memory, and reduced hippocampal volume.
- The hippocampus is sensitive to glucocorticoids, making it vulnerable to the negative effects of chronic stress.
Physiological Effects of Stress
- Stress can affect the musculoskeletal system, causing muscle tension, pain, and stiffness.
- The immune system can be impacted, leading to suppressed immune function and increased inflammation.
- Stress can also affect the integumentary system, leading to conditions like eczema and poor wound healing.
- Cardiovascular manifestations of stress include hypertension, tachycardia, and cardiovascular disease.
- Stress can affect the gastrointestinal system, leading to digestive issues, such as irritable bowel syndrome (IBS).
- The genitourinary system can be impacted, leading to sexual dysfunction, decreased fertility, and menstrual irregularities.
- Stress can also impact the respiratory system, leading to rapid breathing, asthma, and chronic obstructive pulmonary disease (COPD).
Emotional and Psychological Effects of Stress
- Emotional symptoms of stress include anxiety, depression, and mood swings.
- Stress can lead to neuropsychological manifestations such as decreased concentration, memory impairments, and decreased cognitive function.
Consequences of Chronic Stress
- Sustained stress can lead to long-term negative impacts on the hippocampus, including decreased volume and impaired function.
- Chronic stress can also lead to impaired memory, mood disorders, and decreased overall well-being.
