The Genetic Link to Early Onset Alzheimer’s Disease
My mother, who is 53, is starting to exhibit some physical signs associated with aging, and I'm increasingly struck by her resemblance to my grandmother, who is 72. My grandmother has been diagnosed with early onset Alzheimer's, with the official diagnosis probably around the age of 65, although my memory on the exact timing isn't precise. She is the only individual in our family known to suffer from this condition, yet age-related dementia is not rare among our relatives. The fact that my mother is beginning to mirror my grandmother not just physically but potentially mentally is causing me some anxiety. What is the risk that early onset Alzheimer's can be inherited from a mother to her child? Should I be concerned about my own chances, even if my mother remains unaffected? A bit more about my mother: She weighs approximately 160 pounds and has received diagnoses for thyroid problems and degenerative disk disease, a condition similar to that of my great-grandmother. Currently, she isn't taking many medications, though she is advised to consistently take a few. As for my grandmother, I believe she either currently has or had thyroid issues that weren't identified without extensive testing. She has maintained a thin physique throughout her life, did not finish high school, and spent over two decades working for UPS prior to her Alzheimer's diagnosis. In her younger years, she enjoyed social drinking but was never labeled a heavy drinker. Additionally, I think she may be dealing with osteoporosis.

It's understandable to feel concerned about the potential genetic link of Alzheimer's disease in your family. Early-onset Alzheimer's can be inherited, but the overall risk depends on several factors, including family history and individual health conditions.
Explanation
Early-onset Alzheimer's typically affects individuals under 65 and can be hereditary, particularly if there is a known genetic mutation (such as in the PSEN1, PSEN2, or APP genes). While having a grandparent with early-onset Alzheimer's can raise concern, it does not guarantee that your mother—or you—will develop the disease. The majority of Alzheimer’s cases, including late-onset forms, have a complex mix of genetic, environmental, and lifestyle factors.
Here are a few points to consider:
-
Genetic Risk: If your mother is only showing early signs of aging without significant cognitive changes, her risk remains comparatively low. If there's no direct history of early-onset Alzheimer's in your mother's immediate family (like her siblings), her risk of developing it is less than if there were multiple family members affected.
-
Other Contributing Factors: Conditions such as thyroid disorders and degenerative disk disease can contribute to health complications, but they do not directly indicate Alzheimer's risk. However, maintaining overall health is vital since cardiovascular health, physical activity, and diet can influence brain health.
Next Steps
-
Stay Informed: Educate yourself about Alzheimer's disease, its symptoms, and lifestyle factors that can potentially reduce risk, such as maintaining a healthy diet, regular physical activity, and engaging in cognitive-stimulating activities.
-
Monitor Signs: Observe if your mother begins to show cognitive changes (memory loss, confusion, difficulty completing familiar tasks). Keeping track of any changes will be helpful.
-
Encourage Medical Follow-Up: If there are significant concerns or if your mother shows any cognitive decline, it would be wise to encourage her to speak with a healthcare provider who can evaluate her conditions and possibly reference genetic counseling.
-
Focus on Health: Help your mother manage her thyroid condition effectively and promote a healthy lifestyle for both of you. This includes staying active, a balanced diet, and regular health check-ups.
-
Consider Your Own Well-being: It’s normal to feel anxious about potential genetic risks. Consider talking to a counselor or a genetic counselor who can guide you through these feelings and provide more personalized insights.
Acknowledging your concerns is important, and taking proactive steps can help you feel more in control of your health and your mother's health. Remember to seek support from family and friends during this time.

Are My Symptoms Indicating an Impending Stroke?
I’m a young adult female, weighing 99 pounds and standing 5 feet 2 inches tall. I do not smoke, vape, or consume alcohol, and currently, I am undergoing tests for POTS and HEDS. For the past two weeks, I have been experiencing intermittent discomfort in the upper region of my head, particularly in the back and temples. These aren’t typical headaches, but rather sudden twinges of pain that occur sporadically throughout the day. Additionally, over this same period, I have been dealing with bouts of vertigo—probably about 4 to 5 days where it came and went. A few days back, I also encountered a tingling sensation in my arms, which I can’t tell if it was simply due to anxiety. Given that my aunt suffered a stroke in her thirties, the prospect of having a stroke terrifies me. I find that the emergency room here primarily prescribes pain medication if you mention head discomfort, which leaves me uncertain about what steps to take next. Could these symptoms signal an impending stroke? Furthermore, I've also been experiencing pain in my left leg, though I’m unsure if that’s connected to my other symptoms.
Unexplained Symptoms Over the Past Few Years
Greetings, Around three years ago, I started to experience a variety of symptoms that appeared quite abruptly. They seemed to improve briefly, only to return later. This initial onset threw me into a panic, leading me to suspect something severe, like cancer. After consulting my physician, I underwent tests through a neurologist and had multiple lab analyses, yet no definitive diagnosis emerged. Frustrated by the ongoing uncertainty, I ceased my attempts to find answers and have not revisited the doctor for these issues in years. This situation dates back to approximately 2021, coinciding with my time as a nursing student. While I can't be sure if there's a connection, it was around this period that I contracted COVID-19 for the first time and also received my annual flu shot as part of my nursing curriculum. Additionally, I was treated for melanoma during this time, undergoing a Mohs procedure to eliminate it, which was part of the initial anxiety surrounding my symptoms. Below are the symptoms I’ve documented: The first change I noticed was an unrelenting muscle fatigue. Simple tasks such as carrying groceries or working outdoors left me feeling immensely winded. I began to realize that the muscles in my neck felt excessively weak, and my arms and legs, although still functional, felt distinctly weaker than before. Although I could still perform my usual activities, I often felt unsteady, especially when descending stairs. Shortly thereafter, I began suffering from frequent muscle cramps at night and persistent twitching in my muscles during the day, particularly in my legs. I also observed involuntary movements in the inner arches of my feet, which, while somewhat common, were consistently present and unusual for me. Another concerning symptom was the onset of intermittent blurred vision. This issue varies in intensity, making it particularly troublesome during episodes that seem to flare up, often exacerbated by bright lighting, like that from screens or sunlight streaming through open windows. I found myself increasing the font size on screens and printed material because reading became quite challenging. While I haven’t seen an eye care professional yet, the suddenness of these vision problems caught me off guard. Additionally, I observed a significant size disparity between the muscles in my arms; my left arm appeared noticeably bulkier than my right. As a left-handed individual, I had never paid much attention to this before, though it’s possible it’s been like this for some time. The most perplexing symptom, one that’s been difficult to research, involves my right shoulder area. The deltoid region developed an odd squishy sensation. This prompts me to mention the flu and COVID-19 vaccinations. I’ve found no information on this symptom, and inquiries yield little guidance. Initially, it felt as if a lump had developed beneath my deltoid. Gradually, the entire area became squishy, resembling fibrous, lumpy tissue rather than muscle. In contrast, when I flex my left arm, it feels muscular and firm, whereas the right arm feels substantially softer. This strange condition raises questions—could a flaw in the vaccine administration by classmate healthcare students have contributed to this issue, or is it related to my other unexplained symptoms? As for medical evaluations, my Basic Metabolic Panel and Magnesium levels were unremarkable, as was my Complete Blood Count. Further inflammatory markers including CRP, CK, and ESR all returned normal results. My hemoglobin A1c was towards the high end of normal but did not classify as pre-diabetic. Autoimmune tests yielded no significant findings, and a nerve conduction study did not reveal any abnormal results either. The results from an EMG suggested mild increased insertional activity in several tested muscles, though it was deemed possibly normal, yet it might indicate an EMG disease. Unfortunately, I was unable to undergo MRI imaging due to insurance challenges at that time. I am a 42-year-old male with no significant past medical history beyond the prior melanoma and not currently using medication, aside from over-the-counter Benadryl for sleep issues. Apologies for the detailed narrative, but I felt this could be a valuable forum for seeking perspectives. I appreciate your time. It’s important to clarify that I am not prone to hypochondria; prior to these developments, I rarely sought medical care and, oddly enough, didn’t even have a primary care provider when these symptoms began.
Inquiry Regarding FDG-PET Scan Findings
I recently underwent an FDG-PET/CT scan for my brain to investigate some cognitive difficulties I've been experiencing. Although the report is now available on My Chart, my follow-up appointment with the doctor is scheduled for three weeks from now. I have a query regarding the standard deviation scale presented in the report, which lists values from -2 to -4.6. What does the lowest value signify? Is the scale graded on a 1-5, 1-10, or perhaps 1-100 basis? I appreciate your assistance with this! Notable regions noted for decreased metabolic activity include: - Left Inferior frontal gyrus, triangularis: SD "4.6" - Left Heschl gyrus: SD "3.8" - Left Superior temporal gyrus: SD "3.6" - Left Middle temporal gyrus: SD "3.4" - Left Supramarginal gyrus: SD "2.6" - Left Inferior parietal lobule, supramarginal area: SD "2.1" Other areas displaying low metabolism are: - Right Superior frontal gyrus, medial: SD "3.2" - Left Superior frontal gyrus, medial: SD "2.2"
Concerns About Potential Peripheral Artery Disease (PAD)
For the past three to four years, I have been dealing with a persistent numbness in my left foot. Initially, I suspected it might be due to a pinched nerve or perhaps something similar, but the sensation has never completely returned. As time has gone by, I've encountered additional worrying symptoms: - My feet have started to develop a purple hue, particularly evident when I sit in positions that put pressure on my legs or when I take a shower. This discoloration has become one of the most alarming signs of my condition. - The growth of my toenails has slowed considerably, and they now appear uneven and ridged. - Additionally, my feet have a temperature that feels significantly colder than the rest of my body, and they no longer grow hair as they once did. I do not smoke and I’m not diabetic; however, I have high cholesterol and received an elevated result on a lipoprotein test. The prospect of PAD is frightening to me, as it seems synonymous with a grim future. I have been referred to a cardiologist, but they are reluctant to conduct an Ankle-Brachial Index (ABI) test since I am under 35. I want to remain hopeful and believe I don't have PAD, yet I struggle to identify any other plausible explanations for these symptoms. What could be potential alternatives to consider, if any exist?
Unexplained Left Chest Pain, Electric-Like Jabs in Lower Back, and Unusual Headaches
Hi there, I’m a 15-year-old experiencing some peculiar health issues lately. A visit to my doctor led to a diagnosis of anxiety and poor posture after I complained about headaches and strange, electric sensations rising through my head. However, after that appointment, I became aware of pain in my heart and strange discomfort in my left chest accompanied by difficulty breathing. Initially, I thought these symptoms aligned with anxiety, but they persisted long enough to cause concern. To rule out any serious conditions, I underwent a blood test, which fortunately came back normal. Despite the positive results, I continued to feel unusual pains in my heart region and a peculiar ache in my lower abdomen. The doctor had previously mentioned my poor posture and identified an issue with my occipital nerve, which I’ve somewhat addressed. Now, though, I find myself having intermittent back pain and brief discomfort just beneath my left lung. These pains are indeed strange; they don’t always last long, sometimes just fading after five seconds or they might stick around for several minutes. I tend to spend a lot of time in bed and don’t often leave the house, yet when I do, these pains still occur. Thankfully, they aren’t debilitating, but I can't help but feel anxious thinking something might be significantly wrong with my health. It’s unsettling and I’d prefer not to dwell on such thoughts. To summarize: I experience chest pain in my lower left quadrant, specifically near my lung, alongside a mild but uncomfortable sensation that waxes and wanes. Additionally, I suffer from headaches located on the upper left side of my head. I apologize for any grammatical errors as I used voice-to-text for this message. Another detail that might be relevant is that I have recently quit vaping, now almost 22 days ago, and I wonder if this could be part of the recovery process.
