Curing Alzheimer’s Disease with AI : A Unified Multimodal Theory and Approach

Based on extensive research evidence uncovered by the author (see the 4 Horsemen of Aging blog post) , Alzheimer’s disease appears to emerge from a complex, interconnected cascade of aging-related molecular and hormonal changes that work synergistically to drive neurodegeneration 123. This comprehensive analysis reveals how multiple declining and increasing factors create a self-reinforcing cycle of brain dysfunction.

The Four-System Aging Framework

Core Aging Systems and Their Interconnections

The evidence suggests that aging progresses through four evolutionarily-layered systems that co-opt each other’s vulnerabilities 145:

System #1: Structural/Vascular Aging

Primary mechanism: Truncated Lamin A protein (progerin) causes loss of cellular differentiation and vascular degradation
Yamanaka factor: KLF4 provides protection
AD connection: Contributes to blood-brain barrier dysfunction and cerebrovascular pathology

System #2: Mitochondrial Dysfunction

Primary mechanism: Energy production failure in ATP-dependent organs (brain, muscles, eyes)
Yamanaka factor: Sox2 offers neuroprotection
AD connection: Directly impacts neuronal energy metabolism and synaptic function

System #3: DNA Repair Failure

Primary mechanism: Truncated ATM and XP/CS proteins fail to repair DNA damage and suppress ROS
Yamanaka factor: c-Myc provides cellular protection
AD connection: Leads to accumulation of damaged proteins and genomic instability

System #4: Reproductive/Sexual Aging

Primary mechanism: WRN protein deficiency affects stem cell differentiation and genomic stability
Yamanaka factor: Oct4 maintains pluripotency
AD connection: Coordinates all other aging systems through hormonal changes

The Central Orchestrator: Short LARP1

mRNA Splicing Dysfunction as the Master Switch

Short LARP1, a nuclear long non-coding RNA, appears to be the central orchestrator of aging by interfering with proper mRNA splicing of critical protective proteins 12526. This molecule:

Blocks WRN production → Triggers System #4 (reproductive aging)
Truncates ATM and XP/CS mRNAs → Activates System #3 (DNA repair failure)
Indirectly affects mitochondrial function → Compromises System #2 (energy metabolism)
May interfere with Lamin A splicing → Potentially impacts System #1 (structural integrity)

The beauty of this RNA-level sabotage is that it remains potentially reversible, unlike permanent DNA damage, which explains why interventions like Yamanaka factor therapy can restore youthful cellular states 125.

The Hormonal Trigger Cascade

The Melatonin-LH-Progesterone Axis

The hormonal changes that initiate and accelerate Alzheimer’s disease follow a predictable pattern 520 23:

Phase 1: Melatonin Decline (Age 40+)

Pineal gland aging reduces melatonin production by up to 90% 5
Loss of melatonin’s suppressive effect on LH and FSH 23
Reduced antioxidant protection and circadian disruption 9

Phase 2: Gonadotropin Surge (Age 50+)

LH increases by 1000%+ in women, 400%+ in men 516
FSH increases dramatically, especially in men 5
hCG levels rise by ~500% in both sexes 5

Phase 3: Protective Hormone Collapse

Progesterone drops to near-zero in menopausal women 510
DHEA declines by 80-90% 5
Pregnenolone falls dramatically 5

Sex-Specific Pathways

In Women:

High baseline LH levels (10x higher than men) create lifelong brain stress 516
Progesterone provides neuroprotection until menopause 10
Post-menopausal LH surge overwhelms remaining protective mechanisms 516

In Men:

Lower baseline LH levels mean less direct brain attack 5
Gradual progesterone decline around age 70 removes neuroprotection 5
AD progression may be more related to loss of protection than active attack 510

The Metabolic Collapse Triangle

NAD+/FAD Depletion and Energy Crisis

The evidence reveals a coordinated depletion of essential cellular cofactors 18 19 22:

CD38-Mediated NAD+ Depletion:

CD38 expression increases dramatically with aging in multiple tissues 18 19
NAD+ levels decline by ~50% during aging 18 22
Mitochondrial function deteriorates as SIRT3 activity decreases 18

MAO-A/B-Mediated FAD Depletion:

MAO-A increases 4-6 fold in aging heart tissue 6 27 30
MAO-B increases 400%+ in aging brain 6 7
FAD depletion mirrors NAD+ loss, creating ~80% energy production deficit in mitochondria 130

The Perfect Storm:

NAD+ and FAD each contribute ~40% of electron transport chain capacity 118
Combined depletion creates severe ATP deficiency 18 22
Neurons, being highly energy-dependent, suffer disproportionately 11 22

α-Ketoglutarate (αKG) Decline and Epigenetic Dysregulation

αKG serves as a critical metabolic hub whose decline has cascading effects 8 114:

Direct effects: 57% reduction in KGDHC activity in AD brains 8 11
Epigenetic consequences: αKG is required for TDG/tet enzyme function in DNA demethylation 4
Gene silencing: ~36 of Horvath’s 48 aging genes become hypermethylated and silenced 4
Serum decline: 90%+ reduction in circulating αKG levels with aging 4

GABA System Collapse

GABA decline represents both a cause and consequence of the aging cascade 15 21 7:

Mechanisms of GABA Loss:

Age-related reduction in GAD65 enzyme expression adn serum GABA 15
Increased MAO-B activity in astrocytes produces excess GABA 6 7
Hormonal acidity (LH, FSH, hCG) may alter intracellular pH and reduce GABA synthesis 4

Consequences:

Loss of inhibitory neurotransmission 15
Increased excitotoxicity and calcium overload 15
Promotion of M1 macrophage activation and CD38 expression 4
Further acceleration of NAD+ depletion 418
Declining serum GABA (along with magnesium deficiency) leads to beta cell dysregulation impairing insulin production.

The Magnesium-Vitamin D3 Connection

Magnesium: The Missing Cofactor

Magnesium deficiency appears to be both a cause and accelerator of Alzheimer’s pathology 14 171:

Prevalence and Detection:

Up to 80% of elderly populations are magnesium deficient 117
Blood tests miss tissue deficiencies (99% of magnesium is intracellular) 117
AD patients show 18% lower hippocampal magnesium levels 17

Mechanisms in AD:

Required cofactor for over 300 enzymes including those involved in DNA repair 117
Essential for ATP synthesis and mitochondrial function 117
Needed for proper glutathione function and ROS detoxification 1
Critical for NMDA receptor regulation and calcium homeostasis 117

Vitamin D3: The Neuroprotective Hormone

Vitamin D3 decline with aging contributes significantly to cognitive deterioration 12 13 21:

Age-Related Changes:

Skin’s ability to synthesize vitamin D3 declines dramatically with aging 125
Widespread deficiency in 40-100% of elderly populations 13

Neuroprotective Mechanisms:

Enhances synaptic transmission and vesicle trafficking 12
Up-regulates genes involved in neurotransmission including synaptojanin 1 and synaptotagmin 2 12
Reduces GABA-positive reactive astrocytes in AD models 21
Supports myelin structure through contactin 4 and β-1-syntrophin expression 12

The Unified Treatment Protocol

Targeting the Root Causes

Based on this multimodal understanding, an effective treatment must address multiple pathways simultaneously:

Hormonal Restoration:

Melatonin supplementation: 75-120mg nightly to suppress LH and restore antioxidant protection 59
Progesterone therapy: Especially critical for men and post-menopausal women 510
DHEA and pregnenolone: Restore declining protective hormones 5

Cofactor Repletion:

High-dose magnesium: Target tissue deficiency with extended-release forms 117
Vitamin D3 supplementation: Achieve sufficient serum levels (70+ ng/mL) 12 13
NAD+ precursors: Niacin, NMN or NR to combat CD38-mediated depletion 18 19
FAD/Riboflavin: Vitamin B2 Counters MAO-mediated FAD loss 1

Metabolic Support:

αKG supplementation: Restore TCA cycle function and epigenetic regulation 48 11
GABA support: Direct supplementation or GAD enzyme cofactors 415

Targeted Inhibition:

MAO-B inhibitors: Selegiline to reduce oxidative stress and preserve neurotransmitters 6 7
CD38 inhibition: Preserve NAD+ levels 18 19

Precision Medicine Approach

For Women:

Primary focus on LH suppression (Lupron or high-dose melatonin) 5
Progesterone replacement post-menopause 510
Address higher baseline oxidative stress 5

For Men:

Emphasis on progesterone supplementation 510
Moderate melatonin dosing for LH control 5
Focus on mitochondrial support 5

Conclusion: A New Paradigm

This multimodal model reveals Alzheimer’s disease not as a single pathological process, but as the inevitable consequence of evolutionarily-programmed aging systems that co-opt each other’s vulnerabilities 145. The evidence suggests that:

Aging is programmed: The precise coordination of these declining systems suggests evolutionary selection for aging rather than random deterioration 128
RNA-level intervention is key: Since the damage occurs at the mRNA splicing level rather than DNA, aging remains potentially reversible 125 26
Early intervention is critical: The cascade accelerates once multiple systems are compromised, making prevention far more effective than late-stage treatment 45
Combination therapy is essential: No single intervention can address the interconnected nature of this multi-system failure 145

This paradigm shift from viewing Alzheimer’s as an isolated brain disease to understanding it as the culmination of coordinated aging systems opens new therapeutic possibilities and explains why previous single-target approaches have largely failed. The future of Alzheimer’s treatment lies in addressing this complex, interconnected cascade at multiple levels simultaneously.
