How do the average values of key lifestyle, cognitive, and demographic variables differ between individuals diagnosed with Alzheimer's (Diagnosis = 1) and those not diagnosed (Diagnosis = 0)
Demographic Information:
- Age: Patients' ages range from 60 to 90 years, offering
insights into how Alzheimer's disease manifests across
different age groups.
- Gender: Gender is recorded with 0 representing Male and 1
representing Female.
- Ethnicity: Patients' ethnic backgrounds are categorized as
Caucasian, African American, Asian, or Other, allowing for
analysis of Alzheimer's impact across various ethnic
groups.
- Education Level: The dataset includes the educational
background of each patient, from no formal education to
higher education, which may influence cognitive
resilience.
Lifestyle Factors:
- Body Mass Index (BMI): BMI values, ranging from 15 to 40,
are provided for each patient to explore the connection
between physical health and Alzheimer's.
- Smoking Status: Indicates whether the patient is a smoker
(1 for Yes, 0 for No), given that smoking is a risk factor
for various health conditions, including cognitive
decline.
- Alcohol Consumption: The number of alcohol units consumed
per week is recorded, ranging from 0 to 20, to assess its
effect on cognitive health.
- Physical Activity: Hours of weekly physical activity are
listed, with values ranging from 0 to 10, to examine its
relationship with cognitive function.
- Diet Quality: Patients receive a diet quality score from 0
to 10, which might be linked to overall health and
cognitive performance.
- Sleep Quality: Sleep quality is rated on a scale of 4 to
10, considering the connection between poor sleep and
cognitive issues, including Alzheimer's.
Medical History:
- Family History of Alzheimer's: Records whether the patient
has a family history of Alzheimer's disease (1 for Yes, 0
for No), a key factor in genetic predisposition.
- Cardiovascular Disease: Notes the presence of
cardiovascular disease, important due to the link between
heart and brain health.
- Diabetes: Indicates whether the patient has diabetes, as
it increases the risk of Alzheimer's.
- Depression: Records if the patient has a history of
depression, a known risk factor for cognitive decline.
- Head Injury: Includes data on whether the patient has
suffered a head injury, as traumatic brain injuries can
elevate Alzheimer's risk.
- Hypertension: The presence of high blood pressure is
recorded, another significant factor in overall health and
Alzheimer's risk.
Clinical Measurements:
- Blood Pressure (Systolic and Diastolic): Blood pressure
readings are included, with systolic ranging from 90 to
180 mmHg and diastolic from 60 to 120 mmHg, to assess
cardiovascular health.
- Cholesterol Levels: The dataset provides total cholesterol
levels (150-300 mg/dL), as well as LDL (50-200 mg/dL), HDL
(20-100 mg/dL), and triglycerides (50-400 mg/dL), which
are crucial for understanding heart health in relation to
Alzheimer's.
Cognitive and Functional Assessments:
- Mini-Mental State Examination (MMSE) Score: Scores range
from 0 to 30, with lower scores indicating more severe
cognitive impairment, providing a snapshot of cognitive
status.
- Functional Assessment: Functional impairment is scored
from 0 to 10, with lower scores indicating greater
difficulty in daily living, highlighting the impact of
Alzheimer's.
- Memory Complaints: Notes whether the patient has reported
memory issues (1 for Yes, 0 for No), often an early
indicator of Alzheimer's.
- Behavioral Problems: Records the presence of behavioral
issues, which are significant in Alzheimer's progression
and management.
- Activities of Daily Living (ADL) Score: Scores range from
0 to 10, with lower scores indicating more difficulty in
performing daily activities, essential for gauging disease
severity.
Symptoms:
- Confusion and Disorientation: Records whether the patient
experiences confusion or disorientation, common symptoms
in Alzheimer's.
- Personality Changes: Includes information on any
personality changes, a notable aspect of Alzheimer's
disease.
- Difficulty Completing Tasks: Indicates whether the patient
has trouble completing tasks, a key sign of cognitive
decline.
- Forgetfulness: Tracks the presence of forgetfulness, one
of the primary symptoms of Alzheimer's.
Diagnosis Information:
- Alzheimer's Diagnosis Status: Clearly indicates whether
each patient has been diagnosed with Alzheimer's disease
(1 for Yes, 0 for No), allowing for data analysis in the
context of confirmed diagnoses. Confidential Information:
Doctor in Charge: To protect privacy, the dataset uses a
placeholder ("XXXConfid") for the name of the doctor
overseeing each patient, ensuring compliance with
confidentiality standards.
Identify Tasks for your Datasets:
- I want to summarize the distribution of MMSE (Mini-Mental
State Examination) scores across all patients.
- I want to compare the correlation between Age and Memory
Complaints.
- I want to explore unexpected patterns in Physical Activity
and Diagnosis (whether the patient has Alzheimer’s).
- I want to identify patients with high CholesterolTotal who
also suffer from Cardiovascular Disease.
- I want to present the trend of Systolic Blood Pressure
over age groups.
